Each time I try to study someone else’s (cool) JS files, to learn from it, there are always some funky function calls that throw me off. I wish the person could be beside me and just walk me through why they did what they did at each step.

It’s just tough sometimes. I see all these cool projects on GitHub and I go, “let me try to analyse it,” and then I see all these properties too. Sometimes I feel compelled to just check the API but it seems like I’d be going into a blackhole of never-ending API depths.

What are some tips that you JS pros have?
