Script Preparation code:

const elementCount = 1_000_000;
const array = new Array(elementCount);
const f64array = new Float64Array(elementCount);
for (let i = 0; i < elementCount; i++) {
  const value = Math.random();
  array[i] = value;
  f64array[i] = value;
}
const comparator = (a, b) => a - b;

Tests:

Array.prototype.sort
array.sort(comparator);
Float64Array.prototype.sort
f64array.sort();
