I'm a junior developer looking to improve my engineering and architectural skills. I want to get better at identifying good and bad code and learn the best practices and coding conventions. I know I need to learn about system design and am working on that, but I'm still unsure if I have a solid grasp of these concepts. During my internship, I got a glimpse of a large codebase but didn't really understand it fully, mostly because I hesitated to ask questions about the design decisions made. I realize that many choices in code aren't always pre-planned but made based on the situation. Now that I'm encouraged to use large language models for code review, how can I review effectively if I'm not sure what good code looks like? Would reading open-source code from well-established projects help me with this? Any advice or insights would be greatly appreciated!

Just keep exploring! Join coding communities, review code, and ask questions. The more you interact with different pieces of code, the more you'll learn about what works and what doesn’t. Personally, I've noticed major improvements by contributing to open source and troubleshooting different projects.
Reading open source code is so beneficial. Choose a library you frequently use and analyze how it’s structured. Noticing how errors are handled and how concerns are separated is a great lesson. Also, revisiting your code after some time and trying to make changes can help you see what designs work well and which ones are frustrating.
What really helped me was realizing that 'good code' is code that’s easy to understand later on. If it’s clear at first glance, it’s probably good code. I focused on smaller projects, made improvements to them, and that really solidified my understanding.
Absolutely, diving into open source projects is a fantastic idea! Start with smaller projects to avoid feeling overwhelmed. As you read through the code, you'll begin to recognize clean coding patterns, which is essential for learning what 'good code' looks like.
