Script Preparation code:
var hasZero = []; var withoutZero = []; for (var i = 0; i < 100; 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.includes
var tempResult = !!Math.round(Math.random()) ? hasZero.includes(0) : withoutZero.includes(0);
Array.reduce
var tempResult = !!Math.round(Math.random()) ? hasZero.reduce((pre, curr) => pre || curr === 0, false) : withoutZero.reduce((pre, curr) => pre || curr === 0, false);
