Script Preparation code:
AخA
 
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 + splice

     
    var index = arr.findIndex((el) => el === foo);
    var newArr = arr.splice(index, 1);
  • filter

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