Benchmark: UUID methodsdgsdgs1

Script Preparation code:

function generateUUID() { // Public Domain/MIT
    var d = new Date().getTime(); //Timestamp
    var d2 = (performance && performance.now && (performance.now() * 1000)) || 0; //Time in microseconds since page-load or 0 if unsupported
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
        var r = Math.random() * 16; //random number between 0 and 16
        if (d > 0) { //Use timestamp until depleted
            r = (d + r) % 16 | 0;
            d = Math.floor(d / 16);
        } else { //Use microseconds since page-load if supported
            r = (d2 + r) % 16 | 0;
            d2 = Math.floor(d2 / 16);
        }
        return (c === 'x' ? r : (r & 0x3 | 0x8)).toString(16);
    });
}


export const generateUUID2 = () => {
  const hexDigits = '0123456789abcdef';
  let uuid = '';

  for (let i = 0; i < 36; i++) {
    if (i === 8 || i === 13 || i === 18 || i === 23) {
      uuid += '-';
    } else if (i === 14) {
      uuid += '4';
    } else if (i === 19) {
      uuid += hexDigits.substr((Math.random() * 4) | 0, 1);
