Script Preparation code:
var arr = new Array(15000); arr.fill({ id: 0 }); arr = arr.map((el, idx) => el.id = idx); var foo = Math.floor(Math.random() * 15000);
Tests:
findIndex
var index = arr.indexOf(foo);
includes
var index = arr.includes(foo);
map and indexOf
var index = arr.map(o => o.id).indexOf(foo);
