Benchmark: concat vs push vs spread

Tests:

Concat
var a = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); var b = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); var c = a.concat(b);
Spread operator
var a = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); var b = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); var c = [ ...a, ...b ]
Push
var a = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); var b = Array.from({length: 1000}, () => Math.floor(Math.random() * 40)); var c = a.push(...b);
