I liked how Codecademy walked us through the logic behind all the shortcuts they have. For example, they do a lesson on if/else and show us how it can get complicated when dealing with more code and when more items are included. Then in the lesson after, they teach us how to use functions to make the code simpler. It can be a little frustrating to learn something and practice it, then to realize it is useless because there is an easier shortcut. However, I think it is important to understand the logic behind all the shortcuts.
