Benchmark: Some vs. Filter vs. indexOf 1

Script Preparation code:

var hasZero = [];
var withoutZero = [];
for (var i = 0; i < 10000; i++) {
  hasZero.push(Math.floor(Math.random() * 1000));
  withoutZero.push(Math.floor(Math.random() * 1000) + 1)
}

Tests:

Array.some
var tempResult = !!Math.round(Math.random()) ? hasZero.some(v => v === 0) : withoutZero.some(v => v === 0);
Array.filter
var tempResult = !!Math.round(Math.random()) ? hasZero.filter(v => v === 0) : withoutZero.filter(v => v === 0);
Array.indexOf
var tempResult = !!Math.round(Math.random()) ? hasZero.indexOf(0) > -1 : withoutZero.indexOf(0) > -1;
Array.for
var data = !!Math.round(Math.random()) ? hasZero : withoutZero; var action = (a) => a === 0; var length = data.length; var tempResult = false; for (let i = 0; i < length; i++) { const tempResult = action(data[i], i); if (tempResult === true) { break; } }
