Benchmark: for vs index of performance

Script Preparation code:

var size = 10000000

var array = Array.from(Array(size).keys())

Tests:

index of
array.indexOf(Math.trunc(size * 0.8))
for
let target = Math.trunc(size * 0.8); for (let i = 0;i < array.length;i++) { if (array[i] == target){ break; } }
