Benchmark: Splice vs Filter 2

Script Preparation code:

const arr = Array(500).fill(0).map(() => Math.floor(Math.random() * 1000000));

Tests:

Splice
const num = arr[Math.floor(Math.random() * 500)] const index = arr.find(item => item === num) if (index > -1) { arr.splice(index, 1) } arr.push(1)
Filter
const num = arr[Math.floor(Math.random() * 500)] const newArr = arr.filter(item => item !== num) newArr.push(1)
