I know how to use a debugger, at least how to set a breakpoint and step through stuff. I'm sure there are features I'm not familiar with, but I at least understand the fundamentals.

I think part of it is that for the last 5 years , every single language I've used with any kind of professional capacity (JavaScript, Haskell, Erlang, F#, Clojure, Scheme) has had a REPL, so I can quickly play with and reload code, making debuggers a bit less necessary than if I were to do a purely-compiled language.

I definitely would benefit from learning more about performance profilers though. You've given me an idea of reading material for the weekend.
