[email protected] Spec https://github.com/tc39/proposal-string-matchall/ https://tc39.github.io/proposal-string-matchall/ Summary String.prototype.matchAll behaves similarly to String.prototype.match, but returns a full regexp result object for each match in a global or sticky regexp. Motivation This offers a simple way to iterate over matches when access to e.g. capture groups is needed. const string = 'Magic hex numbers: DEADBEEF CAFE 8BADF00D'; const regex = /\b[0-9a-fA-F]+\b/g; for (const match of string.matchAll(regex)) { console.log(match); } // Iteration 1: [ 'DEADBEEF', index: 19, input: 'Magic hex numbers: DEADBEEF CAFE 8BADF00D' ] // Iteration 2: [ 'CAFE', index: 28, input: 'Magic hex numbers: DEADBEEF CAFE 8BADF00D' ] // Iteration 3: [ '8BADF00D', index: 33, input: 'Magic hex numbers: DEADBEEF CAFE 8BADF00D' ] Interoperability risk Firefox: In development - https://bugzilla.mozilla.org/show_bug.cgi?id=1435829 Edge: No public signals Safari: No public signals - https://bugs.webkit.org/show_bug.cgi?id=186694 Web developers: Positive Compatibility risk The spec has undergone a few updates and depending on whether other implementations have kept up, there is a possibility V8 could differ in behavior. At the time of writing, V8 is current with all the latest spec updates and have contributed updates to the test262 test suite to minimize difference between other implementations. V8 tests (mjsunit) as well as all test262 tests pass for this feature. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes Link to entry on the Chrome Platform Status https://www.chromestatus.com/features/5520028858318848 Requesting approval to ship? Yes. Note that since this is a V8/JS feature, this post is just an FYI to blink-dev — no signoff from Blink API owners is required. -- -- v8-dev mailing list [email protected] http://groups.google.com/group/v8-dev --- You received this message because you are subscribed to the Google Groups "v8-dev" group.
