If you find that you're stuck or you're debating between options on how to proceed, it might be beneficial to run a spike. A spike is a means with which you can investigate an idea. Give yourself a time limit or some other limiting metric. Once sufficient knowledge or insight has been gained by the exercise, throw away the results. The purpose of the spike is not to walk away with the working code. The goal should be to gain understanding and provide a better idea of a path forward.
