// In other words (in this case), we're recognizing that the second edit happened after where the first edit

// As it so happens, the same logic applies if the second edit precedes the first edit.  In that case rather

// Whether or not we are in strict parsing mode.  All that changes in strict parsing mode is
// that some tokens that would be considered identifiers may be considered keywords.
//
// When adding more parser context flags, consider which is the more common case that the
// flag will be in.  This should be the 'false' state for that flag.  The reason for this is
// that we don't store data in our nodes unless the value is in the *non-default* state.  So,
// for example, more often than code 'allows-in' (or doesn't 'disallow-in').  We opt for
// 'disallow-in' set to 'false'.  Otherwise, if we had 'allowsIn' set to 'true', then almost
// all nodes would need extra state on them to store this info.
//
// Note: 'allowIn' and 'allowYield' track 1:1 with the [in] and [yield] concepts in the ES6
// grammar specification.
//
// An important thing about these context concepts.  By default they are effectively inherited
// while parsing through every grammar production.  i.e. if you don't change them, then when
// you parse a sub-production, it will have the same context values as the parent production.
// This is great most of the time.  After all, consider all the 'expression' grammar productions
// and how nearly all of them pass along the 'in' and 'yield' context values:
//
// EqualityExpression[In, Yield] :
//      RelationalExpression[?In, ?Yield]
//      EqualityExpression[?In, ?Yield] == RelationalExpression[?In, ?Yield]
//      EqualityExpression[?In, ?Yield] != RelationalExpression[?In, ?Yield]
//      EqualityExpression[?In, ?Yield] === RelationalExpression[?In, ?Yield]
//      EqualityExpression[?In, ?Yield] !== RelationalExpression[?In, ?Yield]
//
// Where you have to be careful is then understanding what the points are in the grammar
// where the values are *not* passed along.  For example:
//
// SingleNameBinding[Yield,GeneratorParameter]
//      [+GeneratorParameter]BindingIdentifier[Yield] Initializer[In]opt
//      [~GeneratorParameter]BindingIdentifier[?Yield]Initializer[In, ?Yield]opt
//
// Here this is saying that if the GeneratorParameter context flag is set, that we should
// explicitly set the 'yield' context flag to false before calling into the BindingIdentifier
// and we should explicitly unset the 'yield' context flag before calling into the Initializer.
// production.  Conversely, if the GeneratorParameter context flag is not set, then we
// should leave the 'yield' context flag alone.
//
// Getting this all correct is tricky and requires careful reading of the grammar to
// understand when these values should be changed versus when they should be inherited.
//
// Note: it should not be necessary to save/restore these flags during speculative/lookahead
// parsing.  These context flags are naturally stored and restored through normal recursive
// descent parsing and unwinding.
var contextFlags;// Whether or not we've had a parse error since creating the last AST node.  If we have
// encountered an error, it will be stored on the next AST node we create.  Parse errors
// can be broken down into three categories:
//
// 1) An error that occurred during scanning.  For example, an unterminated literal, or a
//    character that was completely not understood.
//
// 2) A token was expected, but was not present.  This type of error is commonly produced
//    by the 'parseExpected' function.
//
// 3) A token was present that no parsing function was able to consume.  This type of error
//    only occurs in the 'abortParsingListOrMoveToNextToken' function when the parser
//    decides to skip the token.
//
// In all of these cases, we want to mark the next node as having had an error before it.
// With this mark, we can know in incremental settings if this node can be reused, or if
// we have to reparse it.  If we don't keep this information around, we may just reuse the
// node.  in that event we would then not produce the same errors as we did before, causing
// significant confusion problems.
//
// Note: it is necessary that this value be saved/restored during speculative/lookahead
// parsing.  During lookahead parsing, we will often create a node.  That node will have
// this value attached, and then this value will be set back to 'false'.  If we decide to
// rewind, we must get back to the same value we had prior to the lookahead.
//
// Note: any errors at the end of the file that do not precede a regular node, should get
// attached to the EOF token.

// we always consume arguments if they are there. So we treat "new Foo()" as an

// it is there as part of the *associated* object creation node.  Any additional

//
// Because there are no other places in the grammar now that refer to FunctionExpression

     * Any module resolution kind can be augmented with optional settings: 'baseUrl', 'paths' and 'rootDirs' - they are used to
     * mitigate differences between design time structure of the project and its runtime counterpart so the same import name
     * can be resolved successfully by TypeScript compiler and runtime module loader.
     * If these settings are set then loading procedure will try to use them to resolve module name and it can of failure it will
     * fallback to standard resolution routine.
     *
     * - baseUrl - this setting controls how non-relative module names are resolved. If this setting is specified then non-relative
     * names will be resolved relative to baseUrl: i.e. if baseUrl is '/a/b' then candidate location to resolve module name 'c/d' will
     * be '/a/b/c/d'
     * - paths - this setting can only be used when baseUrl is specified. allows to tune how non-relative module names
     * will be resolved based on the content of the module name.
     * Structure of 'paths' compiler options
     * 'paths': {
     *    pattern-1: [...substitutions],
     *    pattern-2: [...substitutions],
     *    ...
     *    pattern-n: [...substitutions]
     * }
     * Pattern here is a string that can contain zero or one '*' character. During module resolution module name will be matched against
     * all patterns in the list. Matching for patterns that don't contain '*' means that module name must be equal to pattern respecting the case.
     * If pattern contains '*' then to match pattern "<prefix>*<suffix>" module name must start with the <prefix> and end with <suffix>.
     * <MatchedStar> denotes part of the module name between <prefix> and <suffix>.
     * If module name can be matches with multiple patterns then pattern with the longest prefix will be picked.
     * After selecting pattern we'll use list of substitutions to get candidate locations of the module and the try to load module
     * from the candidate location.
     * Substitution is a string that can contain zero or one '*'. To get candidate location from substitution we'll pick every
     * substitution in the list and replace '*' with <MatchedStar> string. If candidate location is not rooted it
     * will be converted to absolute using baseUrl.
     * For example:
     * baseUrl: /a/b/c
     * "paths": {
     *     // match all module names
     *     "*": [
     *         "*",        // use matched name as is,
     *                     // <matched name> will be looked as /a/b/c/<matched name>
     *
     *         "folder1/*" // substitution will convert matched name to 'folder1/<matched name>',
     *                     // since it is not rooted then final candidate location will be /a/b/c/folder1/<matched name>
     *     ],
     *     // match module names that start with 'components/'
     *     "components/*": [ "/root/components/*" ] // substitution will convert /components/folder1/<matched name> to '/root/components/folder1/<matched name>',
     *                                              // it is rooted so it will be final candidate location
     * }
     *
     * 'rootDirs' allows the project to be spreaded across multiple locations and resolve modules with relative names as if
     * they were in the same location. For example lets say there are two files
     * '/local/src/content/file1.ts'
     * '/shared/components/contracts/src/content/protocols/file2.ts'
     * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so
     * if file1 has the following import 'import {x} from "./protocols/file2"' it will be resolved successfully in runtime.
     * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all
     * root dirs were merged together.
     * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ].
     * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file:
     * '/local/src/content/protocols/file2' and try to load it - failure.
     * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will
     * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining
     * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location.

// This is due to the fact that we emit the body of an async function inside of a generator function. As generator
// functions cannot reference `super`, we emit a helper inside of the method body, but outside of the generator. This helper
// uses an arrow function, which is permitted to reference `super`.
//
// There are two primary ways we can access `super` from within an async method. The first is getting the value of a property
// or indexed access on super, either as part of a right-hand-side expression or call expression. The second is when setting the value
// of a property or indexed access, either as part of an assignment expression or destructuring assignment.
//
// The simplest case is reading a value, in which case we will emit something like the following:
//
//  // ts
//  ...
//  async asyncMethod() {
//    let x = await super.asyncMethod();
//    return x;
//  }
//  ...
//
//  // js
//  ...
//  asyncMethod() {
//      const _super = Object.create(null, {
//        asyncMethod: { get: () => super.asyncMethod },
//      });
//      return __awaiter(this, arguments, Promise, function *() {
//          let x = yield _super.asyncMethod.call(this);
//          return x;
//      });
//  }
//  ...
//
// The more complex case is when we wish to assign a value, especially as part of a destructuring assignment. As both cases
// are legal in ES6, but also likely less frequent, we only emit setters if there is an assignment:
//
//  // ts
//  ...
//  async asyncMethod(ar: Promise<any[]>) {
//      [super.a, super.b] = await ar;
//  }
//  ...
//
//  // js
//  ...
//  asyncMethod(ar) {
//      const _super = Object.create(null, {
//        a: { get: () => super.a, set: (v) => super.a = v },
//        b: { get: () => super.b, set: (v) => super.b = v }
//      };
//      return __awaiter(this, arguments, Promise, function *() {
//          [_super.a, _super.b] = yield ar;
//      });
//  }
//  ...
//
// Creating an object that has getter and setters instead of just an accessor function is required for destructuring assignments
// as a call expression cannot be used as the target of a destructuring assignment while a property access can.
//
// For element access expressions (`super[x]`), we emit a generic helper that forwards the element access in both situations.

// because their 'ToString' representation is not equal to their original text.

//
// Here, we test whether 'ToString(ToNumber(name))' is exactly equal to 'name'.
// The '+' prefix operator is equivalent here to applying the abstract ToNumber operation.
// Applying the 'toString()' method on a number gives us the abstract ToString operation on a number.
//

// emit to certain specific cases.
//
// In the simplest case, we emit the class declaration as a let declaration, and
// evaluate decorators after the close of the class body:
//
//  [Example 1]
//  ---------------------------------------------------------------------
//  TypeScript                      | Javascript
//  ---------------------------------------------------------------------
//  @dec                            | let C = class C {
//  class C {                       | }
//  }                               | C = __decorate([dec], C);
//  ---------------------------------------------------------------------
//  @dec                            | let C = class C {
//  export class C {                | }
//  }                               | C = __decorate([dec], C);
//                                  | export { C };
//  ---------------------------------------------------------------------
//
// If a class declaration contains a reference to itself *inside* of the class body,
// this introduces two bindings to the class: One outside of the class body, and one
// inside of the class body. If we apply decorators as in [Example 1] above, there
// is the possibility that the decorator `dec` will return a new value for the
// constructor, which would result in the binding inside of the class no longer
// pointing to the same reference as the binding outside of the class.
//
// As a result, we must instead rewrite all references to the class *inside* of the
// class body to instead point to a local temporary alias for the class:
//
//  [Example 2]
//  ---------------------------------------------------------------------
//  TypeScript                      | Javascript
//  ---------------------------------------------------------------------
//  @dec                            | let C = C_1 = class C {
//  class C {                       |   static x() { return C_1.y; }
//    static x() { return C.y; }    | }
//    static y = 1;                 | C.y = 1;
//  }                               | C = C_1 = __decorate([dec], C);
//                                  | var C_1;
//  ---------------------------------------------------------------------
//  @dec                            | let C = class C {
//  export class C {                |   static x() { return C_1.y; }
//    static x() { return C.y; }    | }
//    static y = 1;                 | C.y = 1;
//  }                               | C = C_1 = __decorate([dec], C);
//                                  | export { C };
//                                  | var C_1;
//  ---------------------------------------------------------------------
//
// If a class declaration is the default export of a module, we instead emit
// the export after the decorated declaration:
//
//  [Example 3]
//  ---------------------------------------------------------------------
//  TypeScript                      | Javascript
//  ---------------------------------------------------------------------
//  @dec                            | let default_1 = class {
//  export default class {          | }
//  }                               | default_1 = __decorate([dec], default_1);
//                                  | export default default_1;
//  ---------------------------------------------------------------------
//  @dec                            | let C = class C {
//  export default class C {        | }
//  }                               | C = __decorate([dec], C);
//                                  | export default C;
//  ---------------------------------------------------------------------
//
// If the class declaration is the default export and a reference to itself
// inside of the class body, we must emit both an alias for the class *and*
// move the export after the declaration:
//
//  [Example 4]
//  ---------------------------------------------------------------------

//    { let x = 1; }

// - Renaming introduces fresh name that should not collide with any
//   existing names, however renamed bindings sometimes also should be
//   explicitly initialized. One particular case: non-captured binding
//   declared inside loop body (but not in loop initializer):
//
//    let x;
//    for (;;) {
//        let x;
//    }
//
//   In downlevel codegen inner 'x' will be renamed so it won't collide

//
//   * Why non-captured binding?
//     - Because if loop contains block scoped binding captured in some
//       function then loop body will be rewritten to have a fresh scope
//       on every iteration so everything will just work.
//
//   * Why loop initializer is excluded?

// Many functions in this transformer will contain comments indicating the expected
// intermediate representation. For illustrative purposes, the following intermediate
// language is used to define this intermediate representation:
//
//  .nop                            - Performs no operation.
//  .local NAME, ...                - Define local variable declarations.
//  .mark LABEL                     - Mark the location of a label.
//  .br LABEL                       - Jump to a label. If jumping out of a protected
//                                    region, all .finally blocks are executed.
//  .brtrue LABEL, (x)              - Jump to a label IIF the expression `x` is truthy.
//                                    If jumping out of a protected region, all .finally
//                                    blocks are executed.
//  .brfalse LABEL, (x)             - Jump to a label IIF the expression `x` is falsey.
//                                    If jumping out of a protected region, all .finally
//                                    blocks are executed.
//  .yield (x)                      - Yield the value of the optional expression `x`.
//                                    Resume at the next label.
//  .yieldstar (x)                  - Delegate yield to the value of the optional
//                                    expression `x`. Resume at the next label.
//                                    NOTE: `x` must be an Iterator, not an Iterable.
//  .loop CONTINUE, BREAK           - Marks the beginning of a loop. Any "continue" or
//                                    "break" abrupt completions jump to the CONTINUE or
//                                    BREAK labels, respectively.
//  .endloop                        - Marks the end of a loop.
//  .with (x)                       - Marks the beginning of a WithStatement block, using
//                                    the supplied expression.
//  .endwith                        - Marks the end of a WithStatement.
//  .switch                         - Marks the beginning of a SwitchStatement.
//  .endswitch                      - Marks the end of a SwitchStatement.
//  .labeled NAME                   - Marks the beginning of a LabeledStatement with the
//                                    supplied name.
//  .endlabeled                     - Marks the end of a LabeledStatement.
//  .try TRY, CATCH, FINALLY, END   - Marks the beginning of a protected region, and the
//                                    labels for each block.
//  .catch (x)                      - Marks the beginning of a catch block.
//  .finally                        - Marks the beginning of a finally block.
//  .endfinally                     - Marks the end of a finally block.
//  .endtry                         - Marks the end of a protected region.
//  .throw (x)                      - Throws the value of the expression `x`.
//  .return (x)                     - Returns the value of the expression `x`.
//
// In addition, the illustrative intermediate representation introduces some special
// variables:
//
//  %sent%                          - Either returns the next value sent to the generator,
//                                    returns the result of a delegated yield, or throws
//                                    the exception sent to the generator.
//  %error%                         - Returns the value of the current exception in a
//                                    catch block.
//
// This intermediate representation is then compiled into JavaScript syntax. The resulting
// compilation output looks something like the following:
//
//  function f() {
//      var /*locals*/;
//      /*functions*/
//      return __generator(function (state) {
//          switch (state.label) {
//              /*cases per label*/
//          }
//      });
//  }
//
// Each of the above instructions corresponds to JavaScript emit similar to the following:
//
//  .local NAME                   | var NAME;
// -------------------------------|----------------------------------------------
//  .mark LABEL                   | case LABEL:

// semantics of an ES2015 generator function. When called, this helper returns an
// object that implements the Iterator protocol, in that it has `next`, `return`, and
// `throw` methods that step through the generator when invoked.
//
// parameters:
//  @param thisArg  The value to use as the `this` binding for the transformed generator body.
//  @param body     A function that acts as the transformed generator body.
//
// variables:
//  _       Persistent state for the generator that is shared between the helper and the
//          generator body. The state object has the following members:
//            sent() - A method that returns or throws the current completion value.
//            label  - The next point at which to resume evaluation of the generator body.
//            trys   - A stack of protected regions (try/catch/finally blocks).
//            ops    - A stack of pending instructions when inside of a finally block.
//  f       A value indicating whether the generator is executing.
//  y       An iterator to delegate for a yield*.
//  t       A temporary variable that holds one of the following values (note that these
//          cases do not overlap):
//          - The completion value when resuming from a `yield` or `yield*`.
//          - The error value for a catch block.
//          - The current protected region (array of try/catch/finally/end labels).
//          - The verb (`next`, `throw`, or `return` method) to delegate to the expression
//            of a `yield*`.
//          - The result of evaluating the verb delegated to the expression of a `yield*`.
//
// functions:
//  verb(n)     Creates a bound callback to the `step` function for opcode `n`.
//  step(op)    Evaluates opcodes in a generator body until execution is suspended or
//              completed.
//
// The __generator helper understands a limited set of instructions:
//  0: next(value?)     - Start or resume the generator with the specified value.
//  1: throw(error)     - Resume the generator with an exception. If the generator is
//                        suspended inside of one or more protected regions, evaluates
//                        any intervening finally blocks between the current label and
//                        the nearest catch block or function boundary. If uncaught, the
//                        exception is thrown to the caller.
//  2: return(value?)   - Resume the generator as if with a return. If the generator is
//                        suspended inside of one or more protected regions, evaluates any
//                        intervening finally blocks.
//  3: break(label)     - Jump to the specified label. If the label is outside of the
//                        current protected region, evaluates any intervening finally
//                        blocks.
//  4: yield(value?)    - Yield execution to the caller with an optional value. When
//                        resumed, the generator will continue at the next label.
//  5: yield*(value)    - Delegates evaluation to the supplied iterator. When
//                        delegation completes, the generator will continue at the next
//                        label.
//  6: catch(error)     - Handles an exception thrown from within the generator body. If
//                        the current label is inside of one or more protected regions,
//                        evaluates any intervening finally blocks between the current
//                        label and the nearest catch block or function boundary. If
//                        uncaught, the exception is thrown to the caller.
//  7: endfinally       - Ends a finally block, resuming the last instruction prior to
//                        entering a finally block.
//
// For examples of how these are used, see the comments in ./transformers/generators.ts

// a transform stream is a readable/writable stream where you do
// something with the data.  Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored.  (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation.  For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes.  When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up.  When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer.  When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks.  If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk.  However,
// a pathological inflate type of transform can cause excessive buffering
// here.  For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output.  In this case, you could write a very small
// amount of input, and end up with a very large amount of output.  In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform.  A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

 * already parsed to an object). According to the spec, source maps have the
 * following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - sources: An array of URLs to the original source files.
 *   - names: An array of identifiers which can be referrenced by individual mappings.
 *   - sourceRoot: Optional. The URL root from which all sources are relative.
 *   - sourcesContent: Optional. An array of contents of the original source files.
 *   - mappings: A string of base64 VLQs which contain the actual mappings.
 *   - file: Optional. The generated file this source map is associated with.
 *
 * Here is an example source map, taken from the source map spec[0]:
 *
 *     {
 *       version : 3,

 *       names: ["src", "maps", "are", "fun"],
 *       mappings: "AA,AB;;ABCDE;"

 * The second parameter, if given, is a string whose value is the URL
 * at which the source map was found.  This URL is used to compute the
 * sources array.

/**
 * An IndexedSourceMapConsumer instance represents a parsed source map which
 * we can query for information. It differs from BasicSourceMapConsumer in
 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
 * input.
 *
 * The first parameter is a raw source map (either as a JSON string, or already
 * parsed to an object). According to the spec for indexed source maps, they
 * have the following attributes:
 *
 *   - version: Which version of the source map spec this map is following.
 *   - file: Optional. The generated file this source map is associated with.
 *   - sections: A list of section definitions.
 *
 * Each value under the "sections" field has two fields:
 *   - offset: The offset into the original specified at which this section
 *       begins to apply, defined as an object with a "line" and "column"
 *       field.
 *   - map: A source map definition. This source map could also be indexed,
 *       but doesn't have to be.
 *
 * Instead of the "map" field, it's also possible to have a "url" field
 * specifying a URL to retrieve a source map from, but that's currently
 * unsupported.
 *
 * Here's an example source map, taken from the source map spec[0], but
 * modified to omit a section which uses the "url" field.
 *
 *  {
 *    version : 3,
 *    file: "app.js",
 *    sections: [{
 *      offset: {line:100, column:10},
 *      map: {
 *        version : 3,
 *        file: "section.js",
 *        sources: ["foo.js", "bar.js"],
 *        names: ["src", "maps", "are", "fun"],
 *        mappings: "AAAA,E;;ABCDE;"
 *      }
 *    }],
 *  }
 *
 * The second parameter, if given, is a string whose value is the URL
 * at which the source map was found.  This URL is used to compute the
 * sources array.
 *

      // was resolved.
    });
    ```
  
    `Promise.race` is deterministic in that only the state of the first
    settled promise matters. For example, even if other promises given to the
    `promises` array argument are resolved, but the first settled promise has
    become rejected before the other promises became fulfilled, the returned
    promise will become rejected:
  
    ```javascript

  /**
    Promise objects represent the eventual result of an asynchronous operation. The
    primary way of interacting with a promise is through its `then` method, which
    registers callbacks to receive either a promise's eventual value or the reason
    why the promise cannot be fulfilled.
  
    Terminology
    -----------
  
    - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
    - `thenable` is an object or function that defines a `then` method.
    - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
    - `exception` is a value that is thrown using the throw statement.
    - `reason` is a value that indicates why a promise was rejected.
    - `settled` the final resting state of a promise, fulfilled or rejected.
  
    A promise can be in one of three states: pending, fulfilled, or rejected.
  
    Promises that are fulfilled have a fulfillment value and are in the fulfilled
    state.  Promises that are rejected have a rejection reason and are in the
    rejected state.  A fulfillment value is never a thenable.
  
    Promises can also be said to *resolve* a value.  If this value is also a
    promise, then the original promise's settled state will match the value's
    settled state.  So a promise that *resolves* a promise that rejects will
    itself reject, and a promise that *resolves* a promise that fulfills will
    itself fulfill.
  
  
    Basic Usage:
    ------------
  
    ```js
    let promise = new Promise(function(resolve, reject) {
      // on success
      resolve(value);
  
      // on failure
      reject(reason);
    });
  
    promise.then(function(value) {
      // on fulfillment
    }, function(reason) {
      // on rejection
    });
    ```
  
    Advanced Usage:
    ---------------
  
    Promises shine when abstracting away asynchronous interactions such as
    `XMLHttpRequest`s.
  
    ```js
    function getJSON(url) {
      return new Promise(function(resolve, reject){
        let xhr = new XMLHttpRequest();
  
        xhr.open('GET', url);
        xhr.onreadystatechange = handler;
        xhr.responseType = 'json';
        xhr.setRequestHeader('Accept', 'application/json');
        xhr.send();
  
        function handler() {
          if (this.readyState === this.DONE) {
            if (this.status === 200) {
              resolve(this.response);
            } else {
              reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
            }
          }
        };
      });
    }
  
    getJSON('/posts.json').then(function(json) {
      // on fulfillment
    }, function(reason) {
      // on rejection
    });
    ```
  
    Unlike callbacks, promises are great composable primitives.
  
    ```js
    Promise.all([
      getJSON('/posts'),
      getJSON('/comments')
    ]).then(function(values){
      values[0] // => postsJSON
      values[1] // => commentsJSON
  
      return values;
    });
    ```
  
    @class Promise
    @param {Function} resolver

    @constructor

  var Promise$1 = function () {
    function Promise(resolver) {
      this[PROMISE_ID] = nextId();
      this._result = this._state = undefined;
      this._subscribers = [];

      if (noop !== resolver) {
        typeof resolver !== 'function' && needsResolver();
        this instanceof Promise ? initializePromise(this, resolver) : needsNew();
      }
    }
    /**
    The primary way of interacting with a promise is through its `then` method,
    which registers callbacks to receive either a promise's eventual value or the
    reason why the promise cannot be fulfilled.
     ```js
    findUser().then(function(user){
      // user is available
    }, function(reason){
      // user is unavailable, and you are given the reason why
    });
    ```
     Chaining
    --------
     The return value of `then` is itself a promise.  This second, 'downstream'
    promise is resolved with the return value of the first promise's fulfillment
    or rejection handler, or rejected if the handler throws an exception.
     ```js
    findUser().then(function (user) {
      return user.name;
    }, function (reason) {
      return 'default name';
    }).then(function (userName) {
      // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
      // will be `'default name'`
    });
     findUser().then(function (user) {
      throw new Error('Found user, but still unhappy');
    }, function (reason) {
      throw new Error('`findUser` rejected and we're unhappy');
    }).then(function (value) {
      // never reached
    }, function (reason) {
      // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
      // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
    });
    ```
    If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
     ```js
    findUser().then(function (user) {
      throw new PedagogicalException('Upstream error');
    }).then(function (value) {
      // never reached
    }).then(function (value) {
      // never reached
    }, function (reason) {
      // The `PedgagocialException` is propagated all the way down to here
    });
    ```
     Assimilation
    ------------
     Sometimes the value you want to propagate to a downstream promise can only be
    retrieved asynchronously. This can be achieved by returning a promise in the
    fulfillment or rejection handler. The downstream promise will then be pending
    until the returned promise is settled. This is called *assimilation*.
     ```js
    findUser().then(function (user) {
      return findCommentsByAuthor(user);
    }).then(function (comments) {
      // The user's comments are now available
    });
    ```
     If the assimliated promise rejects, then the downstream promise will also reject.
     ```js
    findUser().then(function (user) {
      return findCommentsByAuthor(user);
    }).then(function (comments) {
      // If `findCommentsByAuthor` fulfills, we'll have the value here
    }, function (reason) {
      // If `findCommentsByAuthor` rejects, we'll have the reason here
    });
    ```
     Simple Example
    --------------
     Synchronous Example
     ```javascript
    let result;
     try {
      result = findResult();
      // success
    } catch(reason) {
      // failure
    }
    ```
     Errback Example
     ```js
    findResult(function(result, err){
      if (err) {
        // failure
      } else {
        // success
      }
    });
    ```
     Promise Example;
