Is there an idiots guide to thinking like a coder?
I'm trying to teach myself how to use expressions in After Effects without having to constantly look for video tutorials or copy and paste stuff that other people have already written.
The biggest problem I'm having is that once I look at something that's more than a few lines long my brain just goes 'huh?' and it's like I'm looking at hieroglyphics. I don't think it's really the syntax... it more a case or 'why is that there?'. For example, say someone defines a variable named 'x'. Then later on x appears as arguments inside other objects and I just find myself thinking 'how did the person who wrote this code make the connections that led them to place 'x' in all the right places in order for it to work the way they wanted it to?'
My question is this...
Is there some kind of 'idiots guide' to thinking like a coder or programmer that I can use as a reference, or that will help me to understand how people figure out their expressions? I don't mean a 'how to think like a coder' book... I really do mean an 'idiots guide'.
