Discussion on: Codebase is too large. Any tips on how you quickly understood existing codebase on your first job?

Personally, I found out that it's easier to get familiarized with a project while just working on real tasks.

However, I have some suggestions to get some initial knowledge:

• get the general information about the main project purposes and features from the team
• great that they use TDD, tests also serve as documentation, so I recommend inspecting the tests
• look at the code structure, find out how the main features work
• trying to refactor parts of the app can also help to understand it better
