Benchmark: JS Find vs FindIndex vs loop

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:

Find
var tempResult = !!Math.round(Math.random()) ? hasZero.find(v => v === 0) : withoutZero.find(v => v === 0);
FindIndex
var tempResult = !!Math.round(Math.random()) ? hasZero.findIndex(v => v === 0) : withoutZero.findIndex(v => v === 0);
loop
var index = 0; var tempResult = null; if (!!Math.round(Math.random())) { for (let item of hasZero) { if (item == 0) { tempResult = index; break; } else index++; } } else { for (let item of withoutZero) { if (item == 0) { tempResult = index; break; } else index++; } }
