Benchmark: Array filter performance

Script Preparation code:

var arr = [];
for (var i = 0; i < 1000; i++) {
  arr[i] = i;
}

function someFn(i) {
  return (i * 3 * 8 / 1200 * 0.002 / 40 * 0.2);
}

var sumForEach = 0,
  sumReduce = 0,
  sumMap = 0,
  sumFilter = 0,
  sumFor = 0;

Tests:

filter
arr.filter(item => (sumFilter += someFn(item)));
reduce
sumReduce = arr.reduce((lastValue, item) => { return sumReduce += someFn(item); });
