This is something I use to time and optimise jquery selectors and anything else that might need benchmarking.

var work = (function(){
    var _timer,
        
        log = function(what){
            return console && console.log ? console.log(what) : what
        },

        reset = function(){
            _timer = +new Date();
        },
    
        elapsed = function(){
            var e = (+new Date) - _timer;
            return e;
        },

        it = function(fn, times){
            reset();
            while(times--){
                fn()
            }
            return log(elapsed());
        };
    
    return{
        reset: reset,
        elapsed: elapsed,
        it: it
    }
})();

work.it(function(){
    $('#something').find('.child').find('tbody').find('tr').filter(function () {
        return !this.className || (this.className && !this.className.match(/foo|bar/))
    }).length
}, 200);

I think most people think of a hard designer-developer split, as if there is a spectrum with designer on one end and developer on the other.

The more of an engineer you are, the less of a designer you are, and vice versa. Perhaps it is because engineering is more associated with analytical “left brain” thinking and design is seen as a more creative, “right brain” exercise. In reality, this is a false dichotomy, as both designers and developers need to use a combination of divergent and convergent thinking to innovate and problem solve. Both disciplines are more similar than most people (and the internet) make it seem.
