Script Preparation code:

arr.fill({ id: 0 });
arr = arr.map((el, idx) => el.id = idx);
var foo = Math.floor(Math.random() * 15000);

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:

var index = arr.indexOf(foo);
var newArr = [...arr].splice(index, 1);

 
var index = arr.indexOf(foo);var newArr = [...arr].splice(index, 1);

var index = arr.filter(el => el !== foo)

 
var index = arr.filter(el => el !== foo)
