npm i ranges-regex

Quick Take

import { strict as assert } from "assert";

import { rRegex } from "ranges-regex";

const oldString = "The quick brown fox jumps over the lazy dog.";
const result = rRegex(/the/gi, oldString);

// all regex matches, but in Ranges notation (see codsen.com/ranges/):
assert.deepEqual(result, [
  [0, 3],
  [31, 34],
]);

// if you slice the ranges, you'll get original regex caught values:
assert.deepEqual(
  result.map(([from, to]) => oldString.slice(from, to)),
  ["The", "the"],
);
