Benchmark: Remove an item from array; indexOf + splice vs filter 2

Script Preparation code:

var arr = [];
for (var i = 0; i < 10000; i++) {
  arr.push(Math.floor(Math.random() * 1000));
}
var itemToRemove = arr[Math.floor(Math.random() * 10000)]

Tests:

indexOf + splice
arr.splice(arr.indexOf(itemToRemove), 1)
filter
arr = arr.filter(el => el !== itemToRemove)
