Benchmark: Javascript string.endsWith vs string.slice and triple equal

Script Preparation code:

function compareEndsWith(val, comparator) {
  return val.endsWith(comparator)
}
function compareSliceMethod(val, comparator) {
  const thingToCompare = val.slice(-comparator.length)
  return thingToCompare === comparator
}

Tests:

endWith
const value = Math.random().toString().padEnd(20,'0'); const ending = "asdf" compareEndsWith(value, ending)
slice
const value = Math.random().toString().padEnd(20,'0'); const ending = "asdf" compareSliceMethod(value, ending)
