How do we work on someone else code, like to implement a new feature
Hello, quick question, I'm currently doing an internship. Last year also I did an internship where I needed to build something, it was pretty interesting. But this year, what happens is that I was put directly in a team to work on leftover works in their backlog (very boring tasks). Even though it was boring, what I noticed is that the codes have been written by many devs and it rarely happen that we work on something from scratch.
So my question is, say I need to understand the code of what developers did, how do I do that? I mean for example, I started to debug things, I understood what's happening on a high level but there are still things that I feel without knowing what was done initially, from scratch, it's a bit to add/implement something.
So I wanted some ideas on how you guys do when you need to implement some codes in a software that wasn't written by yourself, it's kind of annoying, right? But I do realise that this is what's going to happen when I will work on full time job, just wanted some advice on how to tackle/exit out of this scenarios.

A friendly place for developers to meet other devs, ask questions, get help, and just have a good time 🙂.
