Test name	Executions per second
Array.some	309687.2 Ops/sec
Array.filter	65583.9 Ops/sec
Array.findIndex	274364.9 Ops/sec

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.findIndex
var tempResult = !!Math.round(Math.random()) ? hasZero.findIndex(v => v === 0) : withoutZero.findIndex(v => v === 0);
