Correct iterators prototypes chain, related [#​261](https://togithub.com/zloirock/core-js/issues/261). - Correct Typed Arrays prototypes chain, related [#​378](https://togithub.com/zloirock/core-js/issues/378). - Make the internal state of polyfilled features completely unobservable, [#​146](https://togithub.com/zloirock/core-js/issues/146). - Add validation of receiver's internal class to missed non-generic methods. - Fix descriptors of global properties. - In the version without global pollution, if `Object#toString` does not support `@@​toStringTag`, add to wrapped prototypes own `toString` method with `@@​toStringTag` logic, see [#​199](https://togithub.com/zloirock/core-js/issues/199). - Update standard features and proposals: - `asap` (old stage 0 proposal) replaced by `queueMicrotask` ([a part of HTML spec](https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#dom-queuemicrotask)) - Update [`Observable`](https://togithub.com/tc39/proposal-observable) ([#​257](https://togithub.com/zloirock/core-js/issues/257), [#​276](https://togithub.com/zloirock/core-js/issues/276), etc.) - Update `Array#flatten` -> `Array#flat` and `Array#flatMap` - Update `global` [stage 3 proposal](https://togithub.com/tc39/proposal-global) - rename `global` to `globalThis` - Update `String#matchAll` ([proposal-string-matchall#​17](https://togithub.com/tc39/proposal-string-matchall/pull/17), [proposal-string-matchall#​38](https://togithub.com/tc39/proposal-string-matchall/pull/38), [proposal-string-matchall#​41](https://togithub.com/tc39/proposal-string-matchall/pull/41), etc.) and move to the stage 3 - Update `.name` properties of `String#{trimStart, trimEnd , trimLeft, trimRight}`, move to the stage 3 - Remove mongolian vowel separator (U+180E) from the list of whitespaces for methods like `String#trim` (ES6 -> ES7) - Mark ES2016, ES2017, ES2018, ES2019 features as stable: - `Array#{ flat, flatMap }` - `{ Array, %TypedArray% }#includes` - `Object.{ values, entries}` - `Object.getOwnPropertyDescriptors` - `String#{ padStart, padEnd }` - `String#{ trimStart, trimEnd, trimLeft, trimRight }` - `Promise#finally` - `Symbol.asyncIterator` - `Object#__(define|lookup)[GS]etter__` - Remove obsolete features: - `Error.isError` (withdrawn) - `System.global` and `global` (replaced by `globalThis`) - `Map#toJSON` and `Set#toJSON` (rejected) - `RegExp.escape` (rejected) - `Reflect.enumerate` (removed from the spec) - Unnecessary iteration methods from `CSSRuleList`, `MediaList`, `StyleSheetList` - **No more non-standard features**, finally removed: - `Dict` - `Object.{classof, isObject, define, make}` - `Function#part` - `Number#@​@​iterator` - `String#{escapeHTML, unescapeHTML}` - `delay` - Add `.sham` flag to features which can't be properly polyfilled and / or not recommended for usage: - `Symbol` constructor - we can't add new primitives. `Object.prototype` accessors too expensive. - `Object.{create, defineProperty, defineProperties, getOwnPropertyDescriptor, getOwnPropertyDescriptos}`, `Reflect.{defineProperty, getOwnPropertyDescriptor}` can't be properly polyfilled without descriptors support. - `Object.{freeze, seal, preventExtensions}`, `Reflect.preventExtensions` can't be properly polyfilled in ES3 environment. - `Object.getPrototypeOf` can be deceived in ES3 environment. - `Reflect.construct` can't be polyfilled for a correct work with `newTarget` argument on built-ins. - Typed Array constructors polyfill is quite correct but too expensive. - `URL` constructor in engines without descriptors support. - Bug and compatibility fixes: - Fix deoptimisation of iterators in V8, [#​377](https://togithub.com/zloirock/core-js/issues/377). - Fix import of property before constructor which should contain this property, [#​262](https://togithub.com/zloirock/core-js/issues/262). - Fix some cases of IE11 `WeakMap` frozen keys fallback, [#​384](https://togithub.com/zloirock/core-js/issues/384). - Fix non-enumerable integer keys issue because of Nashorn ~ JDK8 bug, [#​389](https://togithub.com/zloirock/core-js/issues/389). - Fix [Safari 12.0 `Array#reverse` bug](https://bugs.webkit.org/show_bug.cgi?id=188794). - One more fix for microtasks in iOS related [#​339](https://togithub.com/zloirock/core-js/issues/339). - Added a fallback for [Rhino bug](https://togithub.com/mozilla/rhino/issues/346), [#​440](https://togithub.com/zloirock/core-js/issues/440). - Many other internal fixes and improvements. - Repository: - Change `core-js` repository structure to monorepo with packages in `/packages/` directory. - Clean-up it, remove all possible duplicates, generated files, etc. - Packages: - **Extract a version without global namespace pollution to a separate `core-js-pure` package (replacement for `core-js/library`).** - **Leave only one pair of bundles (global, with all polyfills) and move it to `core-js-bundle` package.** - Remove bundling logic from `core-js` package, leave it only in `core-js-builder` package. - Clean-up packages. - Because of all approaches, **reduce size of packages from ~2mb for `core-js@2` to**: - **~500kb for `core-js` package** - **~440kb for `core-js-pure` package** - Finally remove `bower.json` - CommonJS API, namespaces: - Add availability [configuration of aggressiveness](https://togithub.com/zloirock/core-js/blob/master/README.md#configurable-level-of-aggressiveness). - Move `core-js/library` to separate `core-js-pure` package. - Because of removing all non-standard features, we no longer need `core-js/shim` entry point, replace it just with `core-js`. - Move all features from ES5, ES2015, ES2016, ES2017, ES2018 and ES2019 to one namespace for stable ES - it's available as `core-js/es`, all those features in `modules` folder has `es.` prefix. - Change prefix for ES proposals from `es7.` to `esnext.`, they no longer available in `core-js/es7`, use `core-js/stage/*` instead of that. - Rename `core-js(/library)/fn` to `core-js(-pure)/features` for improve readability. - Allow more granular inclusion of features from `/es/` path (for example, `core-js/es/array/from`). - Add `/stable/` entry points as an equal of `/features/` for stable features, without proposals. - Add `/proposals/` entry points for allow include all features from one proposal (for example, `core-js/proposals/reflect-metadata`). - Add `/es|stable|features/instance/` entry points for getting polyfill of the related method for passed instance (could be used in cases like `babel-runtime`). - Split typed arrays polyfills. Now you can, for example, load only required method (for example, `core-js/es/typed-array/from`). - Extract well-known symbols definition from `es.symbol` module for loading only required features, for example, in MS Edge. - Rename `web.dom` namespace to `web.dom-collections`. - Rename `es6.regexp.{match, replace, search, split}` -> `es.string.{match, replace, search, split}` - mainly it's fixes / adding support of well-known symbols to string methods, only in second place adding related methods to regexp prototype. - Relax `/modules/` directory by moving internal modules to `/internals/` directory. - Remove deprecated array entry points: `core-js(/library)/fn/array/{pop, push, reverse, shift, unshift}`. - `core` object no longer available in the global version, entry points which previously returned it now returns `globalThis` object. Also, don't set global `core` property. - Add some missing entry points. - Tools, tests, code quality: - Added `core-js-compat` package with: - Data about the necessity of `core-js` modules and API for getting a list of required `core-js` modules by `browserslist` query, [#​466](https://togithub.com/zloirock/core-js/issues/466). - Data which modules load by each entry point (mainly useful for tools like `@babel/preset-env`). - Data which modules added in minor versions (mainly useful for tools like `@babel/preset-env`). - `core-js-builder` package: - Added `targets` option with `browserslist` query. - Removed an option for generation bundle of a version without global namespace pollution - now it's an odd use case. - Removed UMD wrapper from a generated code of bundles - we don't need it for a global polyfill. - **Getting rid of LiveScript**, usage another language in JS standard library looks strange and impedes usage of tools like ESLint: - Tests are rewritten to JS. - Scripts are rewritten to JS. - Babel with minimalistic config (which should work anywhere) used on tests. - ESLint used on tests and tools. - Source code refactored for improving readability. ### [`v2.6.11`](https://togithub.com/zloirock/core-js/blob/master/CHANGELOG.md#​2611-LEGACY---20191209) [Compare Source](https://togithub.com/zloirock/core-js/compare/v2.6.10...v2.6.11) -
