forEach
1802941.9 Ops/sec
reduce
220613.1 Ops/sec
reduce spread
44333.8 Ops/sec
Script Preparation code:
var a = Array.from({length:100},()=>Math.random()); var b = [];
Tests:
forEach
let b = []; for (let i = 0; i < a.length; i++) { b.push(a[i]) }
reduce
b = a.reduce((a,c)=>c>0.5?a.concat(c):a,[])
reduce spread
b = a.reduce((a,c)=>c>0.5?[...a,c]:a,[])
