convert inner datetime to local in `to_date_string` (#1953)
This Pull Request fixes/closes #1942. `Date.prototype.toDateString` should return a value representing the local date. The Rust `Date` inner value represents UTC time, so it should be adjusted to local time before formatting (see equivalent conversions performed by `to_string` and `to_time_string`). To verify this is working as intended, run the test suite with your OS timezone set to `GMT+0`, then again with `GMT+10`. The test `date_proto_to_date_string` should pass for each. For me (Ubuntu via WSL), this can be done with `sudo dpkg-reconfigure tzdata`. This PR also fixes a couple other test cases that used the wrong month value (as noted at the top of the file, JS months are 0-based while `chrono` months are 1-based). |

add README for crates.io publish (#1952)
This Pull Request closes #1948. It changes the following: - set `readme` in `boa_engine` so `README.md` will be published to crates.io - remove unnecessary `exclude` field from `Cargo.toml` in all apps I was unsure whether using a path outside of the workspace root was allowed for `readme` since it [doesn't get included in the release tarball](https://github.com/rust-lang/cargo/issues/5911), but this exact path is used by [juniper](https://github.com/graphql-rust/juniper/blob/master/juniper/Cargo.toml#L13) and [seems to work there](https://crates.io/crates/juniper). I believe `cargo publish` does a bit more than just uploading the tarball, including pulling the `readme` from any arbitrary path. The default behaviour of `cargo package`/`cargo publish` if neither `exclude` or `include` is specified is to include all files from the package root, excluding - dotfiles - .gitignore'd files - subpackages (any subdirectory with a `Cargo.toml` file) - the `/target` directory There's no need to explicitly exclude files from the parent directory since they're already excluded by default. This can be verified by running `cargo package --list` inside any workspace app: ```plain $ cd boa_wasm $ cargo package --list .gitignore Cargo.toml Cargo.toml.orig src/lib.rs ``` You can read more [here](https://doc.rust-lang.org/cargo/reference/manifest.html#the-exclude-and-include-fields). |

Implement Array.from (#1831)
<!--- Thank you for contributing to Boa! Please fill out the template below, and remove or add any information as you feel neccesary. ---> This Pull Request fixes/closes #1784. There're still a few tests failing, notably: - `iter-set-elem-prop-non-writable` - we don't have generator functions implemented - `calling-from-valid-1-noStrict`, `iter-map-fn-this-non-strict` - `thisArg` in non-strict mode, when undefined, should be inherited (that's what I'm guessing, I haven't confirmed this, but strict counterparts do pass with `thisArg` being `undefined`) - `source-array-boundary`, `elements-deleted-after` - ~~Not sure yet, still investigating, but they also include thisArg, so perhaps function calling has an underlying issue?~~ Failing because `this` on the top level evaluates to an empty object instead of containing everything from the top scope Co-authored-by: HalidOdat <halidodat@gmail.com> |

Fix unreachable panics in compile_access (#1861)
This PR changes the following: - More elegantly handles illegal access statements in compile_access - Adds a slew of previously unhandled illegal access test cases ### Caveats It is very, very likely that you will want to simply restrict unary and assignment operations in the AST. However, this prevents crashes in the meantime with a error that is just slightly less detailed than if it were implemented in AST. |

Extract `Intrinsics` struct from `Context` and cleanup names (#1890)
Building up to #186, this PR extracts an `Intrinsics` struct from `Context`, facilitating a lot the extraction of a `Realm` struct. Also, it adapts the `BuiltIn` trait to be useful for builtins that don't expose a global property on initialization (`Generator`, `TypedArray`, etc.) It changes the following: - Creates an `Intrinsics` struct and refactors `Context` to transfer its intrinsic related fields to `Intrinsics`. - Renames some methods and parameters to better describe their functionality. - Makes `BuiltIn::init` return `Option<JsValue>` to skip global property initialization if the builtin initialization returns `None` |

Remove `toInteger` and document the `string` builtin (#1884)
The ECMAScript 2022 specification removes the `toInteger` method, and replaces it with `toIntegerOrInfinity`, which is arguably better for us since the `JsValue::toInteger` returns an `f64`, which is pretty confusing at times. This pull request removes the `JsValue::to_integer` method, replaces all its calls by `JsValue::to_integer_or_infinity` or others per the spec and documents several methods from the `string` builtin. |

Fix `PropertyKey` to `JsValue` conversion (#1886)
We store string `PropertyKey`s with two enums `String` and `Index` for performance reasons, but the spec does not differentiate between string and index property keys so before conversion to `JsValue` we have to convert to a string. This was failing tests like `Reflect.ownKeys([true, "", 1])` because it was returning (integer numbers) `[1, 2, 3]` instead of `['1', '2', '3']` |

`%NativeError%.[[prototype]]` should be `Error` constructor (#1883)
Before the `%NativeError%` objects (like `TypeError`, `ReferenceError`, etc) `[[prototype]]` field was set to `Function.prototype` but this is wrong it should be the `Error` constructor object itself. This makes the `%NativeError%`s 100% spec compliant :) (except `AggregateError` because its not implemented) |

Cleanup vm stack on function return (#1880)
This cleans up the vm stack on a function return. This is needed because when errors are thrown, there may be still values on the stack that cannot be cleaned up via regular control flow. The change should have little performance impact, because the `Vec::truncate` function does not alter the capacity of the vector. |

Removed reference counted pointers from `JsValue` variants (#1866)
This Pull Request fixes/closes #1864. It changes the following: - Removed `JsBigInt` from `Const` nodes, using a boxed `BigInt` instead. - Modifies the `JsObject` variant so that it has a similar structure to other variants, where the internal structure is private. The size of `JsValue` stays in 2 64-bit words (in a 64-bit system at least), and the size of `Const` also stays the same. I have noticed that we clone tokens too much in the parser, so I was thinking that we should implement a by-value getter for `kind()`. Something like `kind_unwrap()`. |

This Pull Request is related to #1873. It changes the following: - Removes the panic in case a label is not found. I think this should be an early syntax error, but at least we shouldn't panic while we fix the issue with the labels. I think we should solve the issue with labeled statements for 0.15. |

Feature arrays with empty elements (#1870)
This PR adds support for arrays with empty elements e.g. `["", false, , , ]`. Before we were filling the empty places with `undefined`, but this is wrong according to [spec](https://tc39.es/ecma262/#sec-runtime-semantics-arrayaccumulation) there shouldn't be undefined with a index at that place, instead only `length` is incremented. So `[,,,].length == 3` and operations like `[,,,,].indexOf(undefined) == -1`, `[,,,,].lastIndexOf(undefined) == -1` etc. |

Correct pop_on_return behaviour (#1853)
This PR changes the following: - Updates the value of `pop_on_return` after a catch as to prevent VM stack corruption - Adds two test cases which demonstrate the issue and demonstrate that it has been fixed I am unsure if it is possible to abuse the patch provided; one would need to catch from within an array initialisation without calling into another frame (e.g., with a lambda), which I don't think is possible. |

Added conversions from and to serde_json's Value type (#1851)
This Pull Request closes #1693. It changes the following: - It adds a fallible conversion from `serde_json::Value` to `JsValue`, which requires a context. - It adds a fallible conversion from `JsValue` to `serde_json::Value`, which requires a context. - Added examples to the documentation of both methods. - Removed some duplicate and non-needed code that I found while doing this.
