JavaScript performance comparison

Test case created

Info

Does eval cause slowness just by existing?

Preparation code

 
<script>
Benchmark.prototype.setup = function() {
    function nop() { }
    function wasteTime() {
        for (var i = 0; i < Math.PI * 2; i += Math.PI / 360) {
            Math.sin(i);
        }
    }
};
</script>
