Compat data targets improvements:
-
React Native from 0.70 shipped with Hermes as the default engine. However, bundled Hermes versions differ from standalone Hermes releases. So added
react-native
target for React Native with bundled Hermes. -
According to the documentation, Oculus Browser was renamed to Meta Quest Browser, so
oculus
target was renamed toquest
. -
opera_mobile
target name is confusing since it contains data for the Chromium-based Android version, but iOS Opera is Safari-based. Soopera_mobile
target was renamed toopera-android
. -
android
target name is also confusing for someone - that means Android WebView, some think thinks that it's Chrome for Android, but they have some differences. For avoiding confusion, addedchrome-android
target. - For consistency with two previous cases, added
firefox-android
target. - For avoiding breaking changes, the
oculus
andopera_mobile
fields are available in the compat data till the next major release.

Function.prototype.{ call, apply, bind }

- Added
sideEffects
field tocore-js-pure
package.json
for better tree shaking, #1117 - Dropped
semver
dependency fromcore-js-compat
-
semver
package (ironically) added a breaking change and dropped NodeJS 8 support in the minor7.1
version, after thatsemver
incore-js-compat
was pinned to7.0
since for avoiding breaking changes it should support NodeJS 8. However, sincecore-js-compat
is usually used with other packages that usesemver
dependency, it causes multiple duplication ofsemver
in dependencies. So I decided to removesemver
dependency and replace it with a couple of simple helpers.

- Added Deno 1.25 compat data mapping

v3.25.0

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

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 aTypeError
instead ofRangeError
if the result length is more thanMAX_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
- NodeJS <17.9
- 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 theArray
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:
- 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
andcore-js-compat
, now it'smodules
andexclude
options - Added support of entry points, modules, regexes, and arrays of them to those filters
- Missed
targets
option ofcore-js-compat
means that thetargets
filter just will not be applied, so the result will contain modules required for all possible engines
- Stabilized proposals are filtered out from the
- Compat data:
-
.stack
property onDOMException
marked as supported from Deno 1.15 - Added Deno 1.21 compat data mapping

- Added Samsung Internet 17.0 compat data mapping

v3.20.0
- Added
structuredClone
method from the HTML spec, see MDN- Includes all cases of cloning and transferring of required ECMAScript and platform types that can be polyfilled, for the details see the caveats
- Uses native structured cloning algorithm implementations where it's possible
- Includes the new semantic of errors cloning from
html/5749
- Added
DOMException
polyfill, the Web IDL spec, see MDN- Includes
DOMException
and its attributes polyfills with fixes of many different engines bugs - Includes
DOMException#stack
property polyfill in engines that should have it - Reuses native

implementations where it's possible (for example, in old NodeJS where it's not exposed as global)
- Includes
- Added support of
cause
