Note that this is a v8/JavaScript feature, so this post is just an FYI for blink-dev — no signoff from Blink API owners is required.
*Contact emails* jkumme...@chromium.org, n...@chromium.org *Explainer* https://github.com/tc39/proposal-bigint/blob/master/README.md *Spec* https://tc39.github.io/proposal-bigint *Summary* This proposal brings arbitrary-precision integers to JavaScript, along with new TypedArrays with signed and unsigned 64-bit integer elements. *Is this feature supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?* Yes. *Debuggability* As of this writing, DevTools support is being worked on. It will be available before shipping. All the usual DevTools features will work for code containing BigInts. *Interoperability risk* Edge: No public signals Firefox: In development: https://bugzilla.mozilla.org/show_bug.cgi?id=1366287 Safari: In development: https://bugs.webkit.org/show_bug.cgi?id=179001 Web developers: Positive, e.g. https://github.com/tc39/proposal-bigint/issues/53 *Compatibility risk* BigInt literals were invalid syntax before. The "BigInt", "BigInt64Array", "BigUint64Array" constructors could clash with user-defined globals. *Activation risk* The semantics of the BigInt proposal are not polyfillable (it would require operator overloading). *Tests* test262 contains tests for BigInt, BigInt64Array, BigUintArray, which V8 passes. V8 also has its own tests: https://chromium.googlesource.com/v8/v8/+/master/test/mjsunit/harmony/bigint *Tracking bug* crbug.com/v8/6791 *Entry on the feature dashboard* https://www.chromestatus.com/features/5371603852460032 *Requesting approval to ship?* Yes. We would like to ship BigInts on ToT in ~3 weeks, in time for Chrome 67. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
