Test name
Executions per second
Array write
4154.6 Ops/sec
TypedArray write
3860.3 Ops/sec
Script Preparation code:
var array = new Array(100000).fill(0).map(_x => 0); var typedArray = new Uint32Array(100000).fill(0);
Tests:
Array write
const len = array.length; for (let i = 0; i < len; ++i) { array[i] = array[i] + 1; }
TypedArray write
const len2 = typedArray.length; for (let i = 0; i < len2; ++i) { typedArray[i] = typedArray[i] + 1; }
