ifraixedes / nice-syntax-bad-performance.js
Last active August 29, 2015 14:03
It contains some cases where a nice syntax is used in expense of performance
'use strict';
var NUM_ITERATIONS = 99999999;
var i, tmp, tmp2, initTime, stopTime;
// Iteration using for loop assigning the value always
initTime = Date.now();
for (i = 0; i < NUM_ITERATIONS; i++) {
tmp = (i % 2) || tmp;
}

Perfomance difference between looping an array using Array methods and simple boring for loop
'use strict';
var i, tmp, initTime, stopTime;
var arr = Array(99999999);
// Iterate using `for` loop
tmp = 0;
initTime = Date.now();
for (i = 0; i < arr.length; i++) {
tmp += i;
