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().
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"]

const str = "2016-01-02|2019-03-07";
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"]
