thank you bro ;-)

According to this comment on stack overflow, https://stackoverflow.com/a/2472969/27759437, this seems closer to the PHP implementation:

In PHP

$m = microtime(true);
$uniqid = sprintf("%8x%05x", floor($m), ($m - floor($m)) * 1000000);

In TypeScript:

const uniqid = (prefix: string = '', moreEntropy: boolean = false) => {
  const precisionTime = performance.timeOrigin + performance.now();
  const seconds = Math.floor(precisionTime / 1000);
  const part1 = seconds.toString(16).substring(0, 8);

  const microseconds = (precisionTime - seconds * 1000) * 1000;
  const part2 = Math.floor(microseconds)
    .toString(16)
    .substring(0, 5)
    .padStart(5, '0');
  return (
    prefix +
    part1 +
    part2 +
    (moreEntropy ? (Math.random() * 10).toFixed(8).toString() : '')
  );
};
