Does Node.js support the String.MatchAll method?

Question

When I test the code:

let result = 'heymama'.matchAll(/m(a)/g);

I get the error "'heymama'.matchAll is not a function"

When I run the version:

let result = 'heymama'.match(/ma/g);

There's no error.

[`.matchAll`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/matchAll) is a recent addition in JS. — Wiktor Stribiżew, Apr 15 '19 at 14:36

#String.matchAll is supported in Node.js from version 12.0.0

Check out the compatibility on MDN.

Had seen that page but didn't scroll to the compatibility section. Bummer. – KalenGi Apr 15 '19 at 14:46
Was having this problem in Docker with 'node:10-alpine', safe to say upgrading to 'node:14-alpine' fixed it! – Greggz May 22 '21 at 22:16

Before Node 12:

As @dennis-vash alredy pointed out, it's currently not supported in Node.js.

There is this "match-all" npm package alternative though.

const matchAll = require("match-all");

let s = "Hello _World_ and _Mars_";
console.log(matchAll(s, /_([a-z]+)_/gi).toArray());
// => [ "World", "Mars" ]

Are there any packages that include types and can be used in Typescript Node projects? – Jeff Tsui Mar 10 '20 at 21:39
It is supported in Node v12? Maybe this answer was from before he updated his answer? – Drew Delano Nov 29 '21 at 05:19
