Benchmark: Array.splice + Array.indexOf vs Array.filter

HTML Preparation code:

<script>
  const i1 = {};
  const i2 = {};
  const i3 = {};
  const i4 = {};
  const i5 = {};
  const i6 = {};
  const i7 = {};
  const i8 = {};
  const i9 = {};
  const i10 = {};
  const array = [i1, i2, i3, i4, i5, i6, i7, i8, i9, i10];
</script>

Script Preparation code:

function spliceIt(array, element){
  const index = array.indexOf(element);
  if (index > -1) array.splice(index, 1);
}

function filterIt(array, element){
  array = array.filter(el => el !== element);
}

Tests:

Splice It
spliceIt(array, i5);
filter It
filterIt(array, i5);
