How Can I Make Sense of Large Codebases?

Gaining experience helps a ton. After working on many projects, you'll start recognizing common structures and patterns. Also, get good at searching your codebase; it’s a valuable skill. If you're stuck, ask your team for help instead of struggling alone.

Honestly, you'll find that it takes a lot of time to get comfortable with larger codebases. Documentation is essential, so if the project has good docs, refer to them to see how components connect. If not, be prepared to dig through the code and seek help from others.

One key thing is to start with the main function or entry point of the project. Don’t stress about understanding every single class right away; just focus on one specific feature at a time and ignore the rest until you get the flow down.

It’s normal to feel overwhelmed! Focus on your immediate task and don’t worry about needing to understand the whole system upfront. "Spaghetti code" is a common issue precisely because it complicates understanding. Just focus on what you need to know to get your job done.

I've been dealing with a legacy project for eight months, and I still don’t understand most of it! Just handle your tasks and don't worry about knowing everything. Chances are, the tickets won't need you to know the entire system.
