Question

Is there a method or process that professionals use to shift through long coding projects?

Answer 1

Not sure if this is what you meant, but if you know what you're looking for and don't want to comb through 500 lines of code, Ctrl+f (on Windows) will bring up the Find/Replace menu. Use it to find certain keywords, replace one string with another, etc.

I already knew that but thanks!

I was wondering more about finding logic errors and making sure to sift through everything and being thorough.

Answer 2

The most important thing is "modularity" -- breaking up large projects into a lot of smaller pieces, each of which can be tested separately. One important example of this is procedural decomposition, where you break up long methods into more small methods (with parameters and return values), that you can test separately.

(There are also some techniques, like "unit testing", that help to make testing the small pieces faster and easier...)
