Benchmark: Filter vs indexOf Speed small sized array 7899

Script Preparation code:


var testArray = [];
for (var i = 0; i < 50; i++) {
  testArray.push(Math.floor(i * 50) + 1)
}

Tests:

remove finding element using indexof
function removeElement(testArray, element) { return ( index = testArray.indexOf(element) !==-1) ? testArray.splice(index, 1):0; } removeElement(testArray, 49);
remove finding element using filter
function removeElement(testArray, element) { return testArray.filter(s => s !== element); } removeElement(testArray, 49);
