Executions per second
Array.prototype.sort
19.1 Ops/sec
Float64Array.prototype.sort
38.2 Ops/sec
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();
