idk man a bunch of nested if statements / redundant tests along with many many unnecessary variable declarations because of not knowing about Objects or Arrays, and wind up doing all the checks and updates manually actually hurts to read, (this is more rare but i should add this as well, because even some people don't even notice it please do not pick up bad consistency's when building a program that includes indenting, syntax, variable naming... etc) which are the most common things that i have ran into when watching earlier people code, it's not there fault though much like with anything learning the simplified mindset is the most important
