My only wish is that tutorials/frameworks would name everything with Foo like iFoo, or listFoo, etc... When using these, I often dont know whats an Object that cannot be changed, and whats a variable. Sure you can play around with it, but I feel like I've lost plenty of time trying to understand other's code.
