Symbol.matchAll
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The Symbol.matchAll static data property represents the well-known symbol Symbol.matchAll. The String.prototype.matchAll() method looks up this symbol on its first argument for the method that returns an iterator, that yields matches of the current object against a string.
For more information, see RegExp.prototype[Symbol.matchAll]() and String.prototype.matchAll().
Try it
const re = /\d+/g;
const str = "2016-01-02|2019-03-07";
const result = re[Symbol.matchAll](str);
console.log(Array.from(result, (x) => x[0]));
// Expected output: Array ["2016", "01", "02", "2019", "03", "07"]
Value
The well-known symbol Symbol.matchAll.

const numbers = {
*[Symbol.matchAll](str) {
for (const n of str.matchAll(/\d+/g)) yield n[0];
},
};
console.log(Array.from(str.matchAll(numbers)));
// ["2016", "01", "02", "2019", "03", "07"]
