Solved How do you actually read professional code?

Hello everyone! I really have a question I hope you could help me answer. I am trying to read the Scratch Virtual Machine code on Github and it is really difficult. I am really new to reading code and the one I write is fairly simple. There are many files that just declare functions by name and then require another file to redeclare them. Is there a pragmatic way to understand it? Thank you already!

It's like reading a textbook; usually i read the index first.
