Release Notes

zloirock/core-js

v3.25.5

Compare Source

  • Fixed regression with an error on reuse of some built-in methods from another realm, #​1133

v3.25.4

Compare Source

  • Added a workaround of a Nashorn bug with Function.prototype.{ call, apply, bind } on string methods, #​1128
  • Updated lists of [Serializable] and [Transferable] objects in the structuredClone polyfill. Mainly, for better error messages if polyfilling of cloning such types is impossible
  • Array.prototype.{ group, groupToMap } marked as supported from V8 ~ Chromium 108
  • Added Electron 22 compat data mapping

v3.25.3

Compare Source

  • Forced polyfilling of Array.prototype.groupToMap in the pure version for returning wrapped Map instances
  • Fixed existence of Array.prototype.{ findLast, findLastIndex } in /stage/4 entry
  • Added Opera Android 71 compat data mapping
  • Some stylistic changes

v3.25.2

Compare Source

  • Considering document.all as a callable in some missed cases
  • Added Safari 16.0 compat data
  • Added iOS Safari 16.0 compat data mapping
  • Fixed some ancient iOS Safari versions compat data mapping

v3.25.1

Compare Source

  • Added some fixes and workarounds of FF30- typed arrays bug that does not properly convert objects to numbers
  • Added sideEffects field to core-js-pure package.json for better tree shaking, #​1117
  • Dropped semver dependency from core-js-compat
    • semver package (ironically) added a breaking change and dropped NodeJS 8 support in the minor 7.1 version, after that semver in core-js-compat was pinned to 7.0 since for avoiding breaking changes it should support NodeJS 8. However, since core-js-compat is usually used with other packages that use semver dependency, it causes multiple duplication of semver in dependencies. So I decided to remove semver dependency and replace it with a couple of simple helpers.
  • Added Bun 0.1.6-0.1.11 compat data
  • Added Deno 1.25 compat data mapping
  • Updated Electron 21 compat data mapping
  • Some stylistic changes, minor fixes, and improvements

v3.25.0

Compare Source

  • Added Object.prototype.__proto__ polyfill
    • It's optional, legacy, and in some cases (mainly because of developers' mistakes) can cause problems, but some libraries depend on it, and most code can't work without the proper libraries' ecosystem
    • Only for modern engines where this feature is missed (like Deno), it's not installed in IE10- since here we have no proper way setting of the prototype
    • Without fixes of early implementations where it's not an accessor since those fixes are impossible
    • Only for the global version
  • Considering document.all as an object in some missed cases, see ECMAScript Annex B 3.6
  • Avoiding unnecessary promise creation and validation result in %WrapForValid(Async)IteratorPrototype%.return, proposal-iterator-helpers/215
  • Fixed omitting the result of proxing .return in %IteratorHelperPrototype%.return, #​1116
  • Fixed the order creation of properties of iteration result object of some iterators (value should be created before done)
  • Fixed some cases of Safari < 13 bug - silent on non-writable array .length setting
  • Fixed ArrayBuffer.length in V8 ~ Chrome 27-
  • Relaxed condition of re-usage native WeakMap for internal states with multiple core-js copies
  • Availability cloning of FileList in the structuredClone polyfill extended to some more old engines versions
  • Some stylistic changes and minor fixes
  • Throwing a TypeError in core-js-compat / core-js-builder in case of passing invalid module names / filters for avoiding unexpected result, related to #​1115
  • Added missed NodeJS 13.2 to esmodules core-js-compat / core-js-builder target
  • Added Electron 21 compat data mapping

v3.22.0

Compare Source

  • Change Array by copy proposal:
    • Moved to Stage 3, March TC39 meeting
    • Disabled forced replacement and added /actual/ entry points for methods from this proposal
    • Array.prototype.toSpliced throws a TypeError instead of RangeError if the result length is more than MAX_SAFE_INTEGER, proposal-change-array-by-copy/70
  • Added some more atob / btoa fixes:
    • NodeJS <17.9 atob does not ignore spaces, node/42530
    • Actual NodeJS atob does not validate encoding, node/42646
    • FF26- implementation does not properly convert argument to string
    • IE / Edge <16 implementation have wrong arity
  • Added /full/ namespace as the replacement for /features/ since it's more descriptive in context of the rest namespaces (/es/ ⊆ /stable/ ⊆ /actual/ ⊆ /full/)
  • Avoided propagation of removed parts of proposals to upper stages. For example, %TypedArray%.prototype.groupBy was removed from the Array grouping proposal a long time ago. We can't completely remove this method since it's a breaking change. But this proposal has been promoted to stage 3 - so the proposal should be promoted without this method, this method should not be available in /actual/ entries - but it should be available in early-stage entries to avoid breakage.
  • Significant internal refactoring and splitting of modules (but without exposing to public API since it will be a breaking change - it will be exposed in the next major version)
  • Bug fixes:
    • Fixed work of non-standard V8 Error features with wrapped Error constructors, #​1061
    • null and undefined allowed as the second argument of structuredClone, #​1056
  • Tooling:
    • Stabilized proposals are filtered out from the core-js-compat -> core-js-builder -> core-js-bundle output. That mean that if the output contains, for example, es.object.has-own, the legacy reference to it, esnext.object.has-own, no longer added.
    • Aligned modules filters of core-js-builder and core-js-compat, now it's modules and exclude options
    • Added support of entry points, modules, regexes, and arrays of them to those filters
    • Missed targets option of core-js-compat means that the targets filter just will not be applied, so the result will contain modules required for all possible engines
  • Compat data:
    • .stack property on DOMException marked as supported from Deno 1.15
    • Added Deno 1.21 compat data mapping
    • Added Electron 19.0 and updated 18.0 compat data mapping
