I mostly work in Clojure and I've noticed this as well, it is usually more efficient to just write it myself if I know what I want to do. However for a language or stack I don't understand well where I just need something quick and dirty it really shines... I had to work with a JS visualization library and got it to write what I needed over 10-15 iterations, much faster than if I actually had to learn the library. General programming knowledge sufficed for noticing things that didn't look right and since the output was visual that helped to sanity check the output as well.
