Benchmark: cached for loop vs for each

Script Preparation code:

var arr = [];
var count = 1000;
for(var i = 0; i<count; i++)
{
  arr.push(i);
}

Tests:

cached for loop
var arrLen = arr.length; var sum = 0; for (var i = 0; i < arrLen; i++){ sum = arr[i]; }
foreach loop
var sum = 0; arr.forEach(elem => { sum = elem; });
