Benchmark: Array.some vs. for..of + Break

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);
for..of + break
var found = false; for (var element of Math.round(Math.random()) ? hasZero : withoutZero) { if (element === 0) { found = true; break; } }
