I learnt programming by making cheats for games and reverse engineering them. It was a fun experience as it wasn't always easy to start with C++ and assembly but it was definitely worth it. Though when you come from a low level language such as C++, looking at highly abstract languages such as Javascript makes everything feel wrong in Javascript, especially when it comes to types and how you can just switch types in the middle of the code :D. But it also gives you an understanding of how Javascript could be implemented, what the engine is doing in the background when you create an object etc..
