Implement Array.at #39578
Description
Activity
The way node.js gets support for language features/changes is through V8, which handles all of the JavaScript parsing and execution. If/When V8 supports whatever change, then node.js will (eventually) support it.
In the particular case of
Array.prototype.at, it's already available in the version of V8 in the master branch. At the very least it will be in the next major version of node.js, but in general V8 version upgrades often get backported to other existing, supported version branches as well, so you just have to wait (or make your own attempt at backporting the necessary V8 upgrades and submitting a PR appropriately if you want to see features in existing version branches sooner).Thanks for the explanation. I was thrown off by the fact that the MDN page says that Chrome already supports it, but nodejs does not, despite them both using V8.
FWIW Support for
Array.atis one of the notable changes for the proposed Node.js 16.6.0: #39534
