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);
var result;

Tests:

findIndex
arr.findIndex((itm) => itm.id === foo);
forEach
arr.forEach((i, index) => { if (arr[i].id === foo) { result = i }; })
