Documentation Updates (#2463)
<!--- Thank you for contributing to Boa! Please fill out the template below, and remove or add any information as you feel necessary. ---> Submitting this as a draft for feedback/second opinions. This draft contains some changes to the documentation. Quick Overview: - Potential `Boa` header for Boa's crates added to `boa_engine`. - Changes the wording to a lot of module headers (See `builtins` module and `object/builtins` module). - Updating built-in wrapper's code examples to use `?` operator. - Adds the doc logo URL to a few crates that didn't have it. The main idea of this draft is to move away from the "This module implements" wording as it feels a bit duplicative when listed under the Modules section (mainly focusing around changes in `boa_engine` to start). While working on this, I had a question about whether we should be using JavaScript or ECMAScript in the Boa's documentation. We do seem to currently use both, and this draft uses JavaScript heavily in the wording. |

Restructure lint lists in `boa_engine` (#2455)
This Pull Request restructures the lint deny/warn/allow lists in `boa_engine`. It adds a lot of documentation to pup functions. There are still a few clippy lints that are not fixed, mainly regarding casting of number types. Fixing those lints effectiveley would in some cases probably require bigger refactors. This should probably wait for #2449 to be merged, because that PR already fixes that lints regarding the `Date` built-in. |

Implement instruction flowgraph generator (#2422)
This PR is a WIP implementation of a vm instruction flowgraph generator
This aims to make the vm easier to debug and understand for both newcomers and experienced devs.
For example if we have the following code:
```js
let i = 0;
while (i < 10) {
if (i == 3) {
break;
}
i++;
}
```
It generates the following instructions (which is hard to read, especially jumps):
<details>
```
----------------------Compiled Output: '<main>'-----------------------

Bindings:

```
</details>
And the flow graph is generated:
The beginning of the function is marked by the `start` node (in green) and end (in red). In branching the "yes" branch is marked in green and "no" in red.
~~This only generates in [graphviz format](https://en.wikipedia.org/wiki/DOT_(graph_description_language)) (a widely used format) but it would be nice to also generate to a format that `mermaid.js` can understand and that could be put in articles https://github.com/boa-dev/boa-dev.github.io/issues/26~~
TODO:
- [x] Generate graphviz format
- [x] Generate mermaid format
- [x] Programmatically generate colors push and pop env instructions
- [x] Display nested functions in sub-sub-graphs.
- [x] Put under a feature (`"flowgraph"`)
- [x] Handle try/catch, switch instructions
- [x] CLI option for configuring direction of flow (by default it is top down)
- [x] Handle `Throw` instruction (requires keeping track of try blocks)
- [x] Documentation
- [x] Prevent node name collisions (functions with the same name)

Refactor the `Date` builtin (#2449)
Just a general cleanup of the `Date` builtin to use slightly better patterns and to fix our warnings about deprecated functions. About the regressed tests. It seems to be a `chrono` bug, so I opened up an issue (https://github.com/chronotope/chrono/issues/884) for it and they've already opened a PR fixing it (https://github.com/chronotope/chrono/pull/885). However, while checking out the remaining failing tests, I realized there's a more fundamental limitation with the library. Currently, [`chrono`](https://github.com/chronotope/chrono) specifies: > Date types are limited in about +/- 262,000 years from the common epoch. While the [ECMAScript spec](https://tc39.es/ecma262/#sec-time-values-and-time-range) says: > The smaller range supported by a time value as specified in this section is approximately -273,790 to 273,790 years relative to 1970. The range allowed by the spec is barely outside of the range supported by `chrono`! This is why the remaining `Date` tests fail. Seeing that, I would like to ping @djc and @esheppa (the maintainers of `chrono`) to ask if it would be feasible to add a feature, akin to the `large-dates` feature from the `time` crate, that expands the supported range of `chrono`.

VM Fuzzer (#2401)
This Pull Request offers a basic VM fuzzer which relies on implied oracles (namely, "does it crash or timeout?"). It changes the following: - Adds an insns_remaining field to Context, denoting the number of instructions remaining to execute (only available when fuzzing) - Adds a JsNativeError variant, denoting when the number of instructions has been exceeded (only available when fuzzing) - Adds a VM fuzzer which looks for cases where Boa may crash on an input This offers no guarantees about correctness, only assertion violations. Depends on #2400. Any issues I raise in association with this fuzzer will link back to this fuzzer. You may run the fuzzer using the following commands: ```bash $ cd boa_engine $ cargo +nightly fuzz run -s none vm-implied ``` Co-authored-by: Addison Crump <addison.crump@cispa.de> |

Boa Gc implementation draft (#2394)
<!---
Thank you for contributing to Boa! Please fill out the template below, and remove or add any
information as you feel necessary.
--->
Not sure if anyone else may be working on something more substantial/in-depth, but I thought I'd post this. 😄
The basic rundown is that this is more of an untested (and in some ways naïve) draft than anything else. It builds rather heavily on `rust-gc`, and tries to keep plenty of the core aspects so as to not break anything too much, and also to minimize overarching changes were it to actually be merged at some point.
This implementation does add ~~a generational divide (although a little unoptimized) to the heap,~~ a GcAlloc/Collector struct with methods, and an ephemeron implementation that allows for the WeakPair and WeakGc pointers.

Therefore, these would require input to be `this: &JsValue, args: &[JsValue], context: &mut Context` like others and use `this_time_value()`?~~ Fixed using `this_time_value()` 2. ~~`to_string()`- how can I use `Date::to_string()` rather than `alloc::string::ToString`.~~ My bad it compiles, just `rust-analyzer` was showing it as an issue. 3. `set_hours()` and `set_minutes()` - they subtract local timezones when setting the value, e.g. - On further look: ```rust // both function call `builtins:📅:mod.rs#L1038 this.set_data(ObjectData::date(t)); // `ObjectData::date` creates a new `Date` object `object::mods.rs#L423 // | this date is chrono::Date<Tz(TimezoneOffset)> and Tz default is being used here which is GMT+0 pub fn date(date: Date) -> Self { Self { kind: ObjectKind::Date(date), internal_methods: &ORDINARY_INTERNAL_METHODS, } } ``` - BTW, in `object::mod.rs`'s `enum ObjectKind` there is `Date(chrono::Date)` and it requires the generic argument, how is it being bypassed here? - Also in `set_minutes()` step 6, `LocalTime` should be used. ```rust // reference date = 2000-01-01T06:26:53.984 date.set_hours(&[23.into(), 23.into(), 23.into(), 23.into()], context)?; // would add tiemzone(+5:30) to it // Is 2000-01-01T17:53:23.023 // Should be 2000-01-01T23:23:23.023 ``` 4. `parse()` - it uses `chrono::parse_from_rfc3339` internally, while es6 spec recommends ISO8601. And it can also parse other formats like from [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/parse) `04 Dec 1995 00:12:00 GMT` which fails. So what should be done about it. 5. `to_*()` - This is more general, as the internal date object uses `chrono::NaiveDateTime` which doesn't have timezone. It doesn't account for `+4:00` in example below. ```rust // Creates new `Date` object from given rfc3339 string. let date = JsDate::new_from_parse(&JsValue::new("2018-01-26T18:30:09.453+04:00"), context); println!("to_string: {:?}", date2.to_string(context)?); // IS: Sat Jan 27 2018 00:00:09 GMT+0530 // Should: Fri Jan 26 2018 20:00:09 GMT+0530 ``` 6. `to_locale_*()` - requires [`ToDateTimeOptions`](https://402.ecma-international.org/9.0/#sec-todatetimeoptions) and localization would require chrono's `unstable-locales` feature, which is available for `DateTime` and not for `NaiveDateTime`. - I should have looked properly, `to_date_time_options` is already implemented in `builtins::intl`. Anyway, I would still need some tips on how to use it. What would function signature be like in wrapper API, how would `options` be passed to the said API. - So `to_date_time_options()` takes `options: &JsValue` as an argument and build an object from it and fetch properties through `Object.get()`. If I want `options` to be `{ weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' }` what would `JsValue` look like to make it all work. ```rust date.to_locale_date_string(&[JsValue::new("en_EN"), OPTIONS], context)?; // OPTIONS need to be a JsValue which when converted into an object // have these properties { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' }; ``` ### Possible improvements 1. Right now, `object::jsdate::set_full_year()` and alike (input is a slice) are like below, `into()` doesn't feel ergonomic. ```rust #[inline] pub fn set_full_year(&self, values: &[JsValue], context: &mut Context) -> JsResult<JsValue> { Date::set_full_year(&self.inner.clone().into(), values, context) } // Usage date.set_full_year(&[2000.into(), 0.into(), 1.into()], context)?; // How can something like this be made to work #[inline] pub fn set_full_year<T>(&self, values: &[T], context: &mut Context) -> JsResult<JsValue> where T: Into<JsValue>, { | expected reference `&[value::JsValue]` | found reference `&[T]` Date::set_full_year(&self.inner.clone().into(), values, context) } ``` 2. Any other suggestion? |

Parser Idempotency Fuzzer (#2400)
This Pull Request offers a fuzzer which is capable of detecting faults in the parser and interner. It does so by ensuring that the parsed AST remains the same between a parsed source and the result of parsing the `to_interned_string` result of the first parsed source. It changes the following: - Adds a fuzzer for the parser and interner. Any issues I raise in association with this fuzzer will link back to this fuzzer. You may run the fuzzer using the following commands: ```bash $ cd boa_engine $ cargo +nightly fuzz run -s none parser-idempotency ``` Co-authored-by: Addison Crump <addison.crump@cispa.de> |

Reduced boilerplate code in the parser (#2410)
This PR adds an `OrAbrupt` trait, with the `or_abrupt()` function. This function is equivalent to the previous `?.ok_or(ParseError::AbruptEnd)`, but it's cleaner. It's implemented for the parser cursor results types. It also adds an `advance()` function to the parser cursor (which might be possible to optimize further), that just advances the cursor without returning any token. This shows a clearer intent in many places where it's being used. I also used `ParseResult` in more places, since we were not using it in many places. |

Make `JsString` conform to miri tests (#2412)
This PR rewrites some patterns of the `JsString` implementation in order to pass all its miri tests. This can be verified by running: ```bash cargo +nightly miri test -p boa_engine string::tests -- --skip builtins --skip parser ``` Basically, we were doing two operations that were Undefined Behaviour per the [Stacked Borrows](https://github.com/rust-lang/unsafe-code-guidelines/blob/master/wip/stacked-borrows.md) model: - Casting `&JsString` to `&mut RawJsString` to `&[u16]`. The intermediate mutable borrow must not exist, or Miri considers this as Undefined Behaviour. - Trying to access `RawJsString.data` using the dot operator. Miri complains with `this is a zero-size retag ([0x10..0x10]) so the tag in question does not exist anywhere`. To fix this, we can recompute the position of `data` every time we want to access it. |

Replace `contains` and friends with visitors (#2403)
This Pull Request replaces `contains`, `contains_arguments`, `has_direct_super` and `function_contains_super` with visitors. (~1000 removed lines!) Also, the new visitor implementation caught a bug where we weren't setting the home object of async functions, generators and async generators for methods of classes, which caused a stack overflow on `super` calls, and I think that's pretty cool! Next is `var_declared_names`, `lexically_declared_names` and friends, which will be on another PR. |

Extract the ast to a crate (#2402)
This should hopefully improve our compilation times, both from a clean build and from an incremental compilation snapshot. Next would be the parser, but it imports `Context`, so it'll require a bit more work. The number of file changes is obviously big, but almost nothing was changed, I just moved everything to another crate and readjusted the imports of the `parser` module. (Though, I did have to change some details, because there were some functions on the ast that returned `ParseError`s, and the tests had to be moved to the parser) |

Implement AST Visitor pattern (attempt #3) (#2392)
This Pull Request closes no specific issue, but allows for analysis and post-processing passes by both internal and external developers. It changes the following: - Adds a Visitor trait, to be implemented by visitors of a particular node type. - Adds `Type`Visitor traits which offer access to private members of a node. - Adds an example which demonstrates the use of Visitor traits by walking over an AST and printing its contents. At this time, the PR is more of a demonstration of intent rather than a full PR. Once it's in a satisfactory state, I'll mark it as not a draft.

Fix order dependent execution in assignment. (#2378)
Fixes #1917 (fixes the code example given with the hashes) Fixes the order dependent execution of assignment, so the following code works correctly: ```javascript function f(x) { console.log(x) } // used to check the order of execution let a = [[]] (f(1), a)[(f(2), 0)][(f(3), 0)] = (f(4), 123) // 🤮 ``` Prints out: ```bash 1 2 3 4 123 ``` As expected This introduces some opcodes: - ~~`Swap3`: currently used only to keep some previous code working that needs refactoring.~~ - ~~`RotateRight n`: Rotates the `n` top values from the top of the stack to the right by `1`.~~ Already added by #2390 ~~Besides the new opcodes,~~ Some opcodes pop and push order of values on the stack have been changed. To eliminate many swaps and to make this change easier. ~~This PR is still a WIP and needs more refactoring~~ This is now ready for review/merge :) |

Implement optional chains (#2390)
This Pull Request implements optional chains.
Example:
```Javascript
const adventurer = {
name: 'Alice',
cat: {
name: 'Dinah'
}
};
console.log(adventurer.cat?.name); // Dinah
console.log(adventurer.dog?.name); // undefined
```
Since I needed to implement `Opcode::RotateLeft`, and #2378 had an implementation for `Opcode::RotateRight`, I took the opportunity to integrate both ops into this PR (big thanks to @HalidOdat for the original implementation!).
This PR almost has 100% conformance for the `optional-chaining` test suite. However, there's this one [test](
