Benchmark: create_UUID - MeasureThat.net

Script Preparation code:

function create_UUID1(a){return a?(a^Math.random()*16>>a/4).toString(16):([1e7]+-1e3+-4e3+-8e3+-1e11).replace(/[018]/g,create_UUID1)}
function create_UUID2() {
  var dt = new Date().getTime();
  var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
    var r = (dt + Math.random() * 16) % 16 | 0;
    dt = Math.floor(dt / 16);
    return (c == 'x' ? r : (r & 0x3 | 0x8)).toString(16);
  });
  return uuid;
}
