This Pull Request fixes/closes #2793.
It changes the following:
- Added a condition to the boa_parser/src/parser/expression/left_hand_side/member.rs parse function match operation for the new token that allows for the operation to continue evaluating more tokens when the TARGET keyword follows it.
- Added a test to validate the fix. (Could not figure out the structure of the test suite so it's commented for now). All other tests pass.
Please let me know if there's anything else I can do to improve the fix.

As mentioned in https://github.com/boa-dev/boa/pull/2848#issuecomment-1518909512, this uses our new default ICU4X data to replace `char::is_start` and `char::is_continue` from the `boa_unicode` crate with the [`icu_properties`](https://crates.io/crates/icu_properties) crate.
Note that this doesn't deprecate `boa_unicode` yet, since that'll require some discussion about how to proceed with a now unused sub-crate.
This Pull Request implements [Initializers in ForIn Statement Heads](https://tc39.es/ecma262/#sec-initializers-in-forin-statement-heads) from the Annex B. This also cleans up the "annex-b" feature to be able to disable it with `--no-default-features`, since I couldn't test the error messages when the feature is disabled.
This Pull Request fixes some additional Annex B tests.
It changes the following:
- Fixes bugs related to parsing HTML closing comments (`-->`).
- Implements `RegExp::compile` behind the `annex-b` feature.
- Ignores the `legacy-regexp` feature flag, since it's still stage 3.
Small steps towards ES5 conformance.
This PR changes the following:
- Implements HTML comments parsing (`<!--`, `-->`).
- Gates the functionality behind a new `annex-b` feature for `boa_parser`.
- Renames `strict_mode` to `strict` to be consistent with `Parser::set_strict`.
Currently we have no explicit representation for parenthesized expressions which makes some behaviours impossible to detect. A bonus is that we can now turn AST that contains parenthesized expressions back to code.
This Pull Request changes the following:
- Add an AST node for parenthesized expressions.
- Adjust some conversions and checks to "ignore"/"expand" parenthesized expressions.
- Fix some tests that had parenthesized expressions.
This PR changes the following:
- Adds a new (very simple) security policy, to comply with GitHub standards
- Changes the internal links of the documentation to point to the new boajs.dev domain
- The developer documentation link now lies in the CONTRIBUTING.md file
This Pull Request changes the following:
- Implement `with` statement parsing, ast node, compilation and excution.
- Implement object environments that are used in the `with` statement excution.
The implementation of object environments can probably be optimized further by using more compile-time information about when object environments can exist. Maybe there could also be a separate environment stack for object environments to reduce the filtering and iteration that is needed with the current implementation.
This does not fix all tests in the `test/language/statements/with` suite yet. But for most failing tests that I have looked at we are missing other features / have bugs elsewhere.
As a note for the review:
The functions in the `impl Context` block in `boa_engine/src/environments/runtime.rs` are mostly copied / moved from the existing functions. The only change there should be the addition of the object environment logic. They had to be moved to `Context` because of borrow semantics.

This Pull Request addresses the broken `cargo clippy` lints that is currently causing CI to fail.
This PR migrates our entire test suite to our new testing API.
It changes the following:
- Migrates tests to new test API.
- Cleans up the API to be a bit more descriptive and maintainable.
- Prettifies our test failure display to show the failed scripts.
- Splits our massive `tests.rs` file into smaller sub-suites.
Example output of a failing test:

This Pull Request closes#1907.
It changes the following:
- Implement several early errors relating to labels, `break` and `continue` in the parser.
- Implement an early error for invalid cover grammar of object literals in the parser.
- Remove all remaining syntax errors from the bytecompiler.
I'm creating this draft PR, since I wanted to have some early feedback, and because I though I would have time to finish it last week, but I got caught up with other stuff. Feel free to contribute :)
The main thing here is that I have divided `eval()`, `parse()` and similar functions so that they can decide if they are parsing scripts or modules. Let me know your thoughts.
Then, I was checking the import & export parsing, and I noticed we are using `TokenKind::Identifier` for `IdentifierName`, so I changed that name. An `Identifier` is an `IdentifierName` that isn't a `ReservedWord`. This means we should probably also adapt all `IdentifierReference`, `BindingIdentifier` and so on parsing. I already created an `Identifier` parser.
Something interesting there is that `await` is not a valid `Identifier` if the goal symbol is `Module`, as you can see in the [spec](https://tc39.es/ecma262/#prod-LabelIdentifier), but currently we don't have that information in the `InputElement` enumeration, we only have `Div`, `RegExp` and `TemplateTail`. How could we approach this?

This Pull Request changes the following:
- Implement binary `in` operation with private names.
- Adding a separate `BinaryInPrivate` expression in addition to the existing `Binary` expression seems like the best way to implement this in a typesafe manner. Other methods like adding an enum for the `Binary` lhs result in having to make assertions.
This Pull Request changes the following:
- Move postfix/prefix increment and decrement operations from the `Unary` expression to a new `Update` expression.
- Add a special type for the `Update` expression target as it is very limited in comparision to an `Unary` target.
- This makes bytecode compilation more typesafe for these operations and removes syntax errors from the bytecompiler without introducing panics (see #1907).
Another change extracted from #2411.
This PR changes the following:
- Improves our identifier parsing with a new `Identifier` parser that unifies parsing for `IdentifierReference`, `BindingIdentifier` and `LabelIdentifier`.
- Slightly improves some error messages.
- Extracts our manual initialization of static `Sym`s with a new `static_syms` proc macro.
- Adds `set_module_mode` and `module_mode` to the cursor to prepare for modules.
Slightly related to #2411 since we need an API to pass module files, but more useful for #1760, #1313 and other error reporting issues.
It changes the following:
- Introduces a new `Source` API to store the path of a provided file or `None` if the source is a plain string.
- Improves the display of `boa_tester` to show the path of the tests being run. This also enables hyperlinks to directly jump to the tested file from the VS terminal.
- Adjusts the repo to this change.
Hopefully, this will improve our error display in the future.
Extracted from #2411 to reduce its size a bit.
This PR:
- Renames `Identifier` to `IdentifierName`, which is the name stated in the spec.
- Renames the utility function `check_parser` to `check_script_parser` to prepare for modules.
- Adds some missing `#[inline]` and rewrites some patterns.
This Pull Request changes the following:
- Add early errors for escaped characters in object and class setters and getters.
- Add early errors for escaped characters in class `static`.
- Add early errors for escaped characters in `new.target`.
- Add early errors for legacy octal/decial escapes that are used in string literals before a `"use strict"` directive.
This Pull Request changes the following:
- Remove wrong early errors for static class methods with the computed property name `prototype`.
- Switch static class method definition opcodes from `__define_own_property__` to `define_property_or_throw` to correctly throw runtime errors on property redefinitions.
This Pull Request hanges the following:
- Add early errors for invalid `yield` and `await` usage in function parameters.
- Add missing function types to hoistable ordering.
- Do not attempt to parse `async` with a following line terminator as an async function.
This Pull Request changes the following:
- Do not skip consecutive semicolons while parsing a `StatementList`.
- Expect semicolon in `LexicalDeclaration` and add an special case for `for` loop parsing.
- Adjust `StatementList` compilation to skip empty statements.
- Adjust/add tests to make sure consecutive semicolons are correctly parsed.
This Pull Request fixes various bugs related to classes.
The biggest changes are:
- Changed private names to be unique across multiple classes.
- Changed private name resolution to work via a visitor after a class is parsed. The way class early errors are defined makes it impossible to perform private name resolution while parsing.
- Added function names to class methods.
- Added class name binding to method function environments.
- Separated opcodes for `static` and non-`static` class method definitions to make the above operations possible.
There are still some bugs and further issues with classes but this is already a lot.
