Spec

Summary

Named captures for ECMAScript regular expressions allow developers to create and refer to named capture groups.

Interoperability and Compatibility risk

This is a stage 3 feature. It adds support for new regular expression syntax to specify and reference named captures. Named captures are exposed through the result object returned by RegExp.prototype.exec; and RegExp.prototype[@@replace] is extended to support named captures.

Webkit has shipped this in Safari Tech Preview Release 40.

Firefox and Edge have not implemented this yet.

All V8 and test262 tests pass.

Will this feature be supported on all six Blink platforms?

Yes.

For future reference: this landed in V8 v6.4.49 and should thus be available in Chrome 64.
