Script Preparation code:

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

Tests:

Array.filter
var tempResult = Math.round(Math.random()) ? hasZero.filter(comparer) : withoutZero.filter(comparer);
Array.some
var tempResult = Math.round(Math.random()) ? hasZero.some(comparer) : withoutZero.some(comparer);
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);
