Benchmark created on

Setup

const size = 1024;
const array = Array(size).fill(0);
for (let i = 0; i < size; ++i)
	array[i] = Math.random() * 1000;

Test runner

Ready to run.

Testing in
TestOps/sec
Simple loop i
let sum = 0;
for (let i = 0; i < size; ++i) sum += array[i];

ready
forEach
let sum = 0;
array.forEach(item => sum += item);
ready
