Of course you have to know your tools. I usually start by doing test cases, then writing the real features while spork and whatchr evaluates my new code every time I save. I rarely even open a browser, it's the final thing I do when my tests are green. It doesn't slow me down, and I can be sure that my feature is there and works even when somebody refactors our software.
