Benchmark: indexOf + splice vs. filter

Script Preparation code:

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

Tests:

indexOf + splice
var index = arr.indexOf(idToFilter); var newArray = [...arr].splice(index, 1);
filter
var newArray = arr.filter(e => e.id !== idToFilter);
