Timothy Flynn	128675770c	LibJS: Implement Intl.Locale.prototype.variants ... This is a normative change in the ECMA-402 spec. See: e8c995a	2025-06-04 17:11:35 -04:00
aplefull	223c9c91e6	LibJS: Implement rawJSON and isRawJSON functions	2025-04-24 09:33:49 -04:00
Andreas Kling	a0bb31f7a0	LibJS: Make async functions & generators faster with helper types ... Instead of returning internal generator results as ordinary JS::Objects with properties, we now use GeneratorResult and CompletionCell which both inherit from Cell directly and allow efficient access to state. 1.59x speedup on JetStream3/lazy-collections.js :^)	2025-04-01 02:30:42 +02:00
Andreas Kling	f1914893e9	LibJS+LibWeb: Remove more uses of DeprecatedFlyString	2025-03-24 22:27:17 +00:00
Andreas Kling	46a5710238	LibJS: Use FlyString in PropertyKey instead of DeprecatedFlyString ... This required dealing with *substantial* fallout.	2025-03-24 22:27:17 +00:00
Andreas Kling	53da8893ac	LibJS: Replace PropertyKey(char[]) with PropertyKey(FlyString) ... ...and deal with the fallout.	2025-03-24 22:27:17 +00:00

Timothy Flynn	26c2484c2f	LibJS: Implement the AsyncDisposableStack interface ... This is very similar to the DisposableStack interface, except disposal of resources is promise-based.	2025-01-17 20:46:32 +01:00
Timothy Flynn	5cfd50224c	LibJS: Use enums instead of strings in Intl.DurationFormat AOs	2024-12-04 08:01:35 -05:00

Timothy Flynn	a93d32a306	LibJS: Alphabetically sort property keys and error types ... And make ErrorType definitions use a better hanging-indent style, to make it easier to maintain going forward. i.e. instead of: M(VeryLongErrorNameHere, "very long error " "message across multiple " "lines" We now have: M(VeryLongErrorNameHere, "very long error message across multiple " "lines")	2024-11-26 11:35:15 -05:00
Timothy Flynn	6a9aec29d5	LibJS: Remove unused property names and error types ... Held off on this during the Temporal rewrite in favor of just removing these all in one go.	2024-11-26 11:35:15 -05:00
Timothy Flynn	b95528d7b5	LibJS: Stub out Temporal.ZonedDateTime.prototype.getTimeZoneTransition ... We will have to add facilities to determine next/previous time zone transitions. Ideally, ICU can provide this.	2024-11-26 11:00:56 +01:00
Timothy Flynn	f2c19f96f8	LibJS: Implement Temporal.Now	2024-11-25 13:32:58 +01:00
rmg-x	ea20545853	LibJS: Add support for Float16Array ... Implements TC39 stage three proposal for Float16Arrays: https://tc39.es/proposal-float16array	2024-11-10 14:48:20 -07:00
Timothy Flynn	93712b24bf	Everywhere: Hoist the Libraries folder to the top-level	2024-11-10 12:50:45 +01:00
Andreas Kling	13d7c09125	Libraries: Move to Userland/Libraries/	2021-01-12 12:17:46 +01:00
Egor Ananyin	7c9c3a10d3	LibJS: Add almost all Math functions	2020-12-28 19:03:11 +01:00
Luke	be30dc2b18	LibJS: Implement Object.prototype.isPrototypeOf ... Spec: https://tc39.es/ecma262/#sec-object.prototype.isprototypeof	2020-12-28 13:10:07 +01:00
Xavier Cooney	ca0f3db004	LibJS: Implement Array.prototype.sort()	2020-12-27 23:24:33 +01:00
Xavier Cooney	1cf92d39eb	LibJS: Implement String.prototype.endsWith()	2020-12-26 01:09:04 +01:00
Luke	200c7572b7	LibJS: Implement Object.prototype.propertyIsEnumerable ... Spec: https://tc39.es/ecma262/#sec-object.prototype.propertyisenumerable This is used by core-js, which is used by frameworks such as Vue.	2020-12-24 21:00:28 +01:00
Andreas Kling	df2a6cb4ab	LibJS: Add Math.acos() and Math.asin()	2020-12-08 17:49:02 +01:00
Andreas Kling	63b748642a	LibJS: Add Math.atan()	2020-12-08 17:49:02 +01:00
Andreas Kling	cc14b5a6d7	LibJS: Implement a very hackish "arguments" object ... We now lazily create an "arguments" array inside functions when code tries to access it. This doesn't follow the spec at all but still covers a lot of the basic uses of arguments, i.e "arguments.length" and "arguments[n]"	2020-12-05 16:41:41 +01:00
Andreas Kling	e6dadd9e5b	LibJS: Implement parseInt() ... Here's a reasonably faithful implementation of ECMAScript 2021 18.2.5. Some corner cases are not covered, I've left them as FIXME's in the included unit test. Also I had to tweak JS::Value::to_i32() to always convert infinity to zero, which is in accordance with ToInt32 AFAICT.	2020-12-05 13:55:55 +01:00
Linus Groh	32571dfa53	LibJS: Add ArrayBuffer	2020-12-02 23:49:00 +01:00
Linus Groh	ddaab598a7	LibJS: Add TypedArray.BYTES_PER_ELEMENT	2020-12-02 12:52:31 +01:00
Andreas Kling	3565d3c60c	LibJS: Add six typed arrays (signed and unsigned 8/16/32-bit) ... This patch adds six of the standard type arrays and tries to share as much code as possible: - Uint8Array - Uint16Array - Uint32Array - Int8Array - Int16Array - Int32Array	2020-12-01 21:05:25 +01:00
Andreas Kling	2d9d883274	LibJS: Add a basic implementation of String.prototype.substr()	2020-11-29 20:29:49 +01:00
AnotherTest	210a3db44d	LibJS: Implement `RegExpPrototype::exec()' ... This implements *only* the builtin exec() function.	2020-11-27 21:32:41 +01:00
AnotherTest	8ba273a2f3	LibJS: Hook up Regex<ECMA262> to RegExpObject and implement `test()' ... This makes RegExpObject compile and store a Regex<ECMA262>, adds all flag-related properties, and implements `RegExpPrototype.test()` (complete with 'lastIndex' support) :^) It should be noted that this only implements `test()' using the builtin `exec()'.	2020-11-27 21:32:41 +01:00
Andreas Kling	a1029738fd	LibJS: Add some more items to CommonPropertyNames that I missed	2020-10-14 00:10:49 +02:00
Andreas Kling	7b863330dc	LibJS: Cache commonly used FlyStrings in the VM ... Roughly 7% of test-js runtime was spent creating FlyStrings from string literals. This patch frontloads that work and caches all the commonly used names in LibJS on a CommonPropertyNames struct that hangs off VM.	2020-10-13 23:57:45 +02:00
