Benchmark: compute vs mutation

Script Preparation code:

let obj = [],
    result = {},
    count = 0

Tests:

compute
let int = setInterval(qwe, 1) function qwe () { if (count > 2000) { clearInterval(int) } count++ obj.push(count) return obj.forEach((item) => { result[item] = `rand${item}` }) }
mutate
let int = setInterval(qwe, 1) function qwe () { if (count > 2000) { clearInterval(int) } count++ obj.push(count) if (count % 2 === 0) { result[item] = `rand${item}` } }
