Info

Zepto vs. Jquery vs. raw JS for getting an element by id

Preparation code

<script src="//staging-ian.appmobi.com/game/zepto.min.js">
</script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<div id="asdf">
</div>
<script>
Benchmark.prototype.setup = function() {
    function el(string) {
      if (string.charAt(0) === '#') {
        return document.getElementById(string.substr(1, string.length));
      }
    }
   
   
    //to be fair, I'll wrap getElementById in a function and return the object
    var boolean = true;
    function byId(id) {
      if (boolean) return document.getElementById(id);
    }
};
</script>
