New here — sharing what I’ve learned from building, breaking, and debugging

Hey everyone 👋
I’m new to the DEV Community, so I thought I’d introduce myself.
I’ve been spending a good amount of time learning and building software, working with things like JavaScript, Node.js, backend development, databases, APIs, and DSA.
Over time, I’ve learned that development is much less about knowing every technology and much more about knowing how to approach a problem when you don't know the answer immediately.
Some things I've learned through actually building projects:
Debugging is often more valuable than writing the initial code.
Understanding why something works is more important than just making it work.
Good backend development requires thinking about failures, not just successful requests.
DSA becomes easier when you start recognizing patterns instead of memorizing solutions.
Documentation and reading other people's code are skills worth developing early.
I’m joining DEV because I want to start documenting what I learn — not just tutorials, but the mistakes, solutions, and practical things I wish I had understood earlier.
I’ll also be sharing some of the projects I'm working on and what I learn while building them.
Looking forward to learning from everyone here.
What was one development lesson you learned only after building real projects?
