Benchmark: for loop push vs mapFilter

Script Preparation code:

var myLargeArray = [];
for (var i = 0; i < 1 << 12; i++) {
  myLargeArray.push(i); 
}

Tests:

for loop push
const resultsArr = [] myLargeArray.forEach(function(element) { if (element % 2 === 0) { resultsArr.push(element) } });
map filter
myLargeArray .map((element) => (element % 2 === 0 ? element : null)) .filter(evenNumber => (evenNumber !== null));
