Executions per second
for of
158769.2 Ops/sec
forEach
60427.2 Ops/sec
reduce
91042.8 Ops/sec
for i
1699.4 Ops/sec
Script Preparation code:
var arr = []; for(var i=0; i < 10000; i++) { arr.push(Math.floor(Math.random() * Math.floor(10000))); }
Tests:
for of
var sum = 0; for (var e of arr) { sum += e; }
forEach
var sum = 0; arr.forEach(e => {sum += e;})
reduce
var sum = arr.reduce((acm, current) => acm + current);
for i
var sum = 0; for (var i = 0; i < arr.length; i++) { sum += arr[i]; }
