How can I benchmark JavaScript code? [closed]

Answer 1

Just adding a quick timer to the mix, which someone may find useful:

var timer = function(name) {
    var start = new Date();
    return {
        stop: function() {
            var end  = new Date();
            var time = end.getTime() - start.getTime();
            console.log('Timer:', name, 'finished in', time, 'ms');
        }
    }
};

Ideally it would be placed in a class, and not used as a global like I did for example purposes above. Using it would be pretty simple:

var t = timer('Some label');
// code to benchmark
t.stop(); // prints the time elapsed to the js console
