Just built my first React app! Here's what I learned
💡
After weeks of struggling with JavaScript basics, I finally completed my first React project - a simple todo app. Here are the key things I learned:
1. **State Management is Everything** - Understanding useState and useEffect changed the game for me.
2. **Component Thinking** - Breaking UI into small, reusable pieces makes everything cleaner.
3. **The React Docs are Gold** - Seriously, the new React docs are incredibly well-written.
For anyone starting out, my advice is to just build things. Don't get stuck in tutorial hell. Pick a project and figure it out as you go.
Happy to answer any questions from fellow beginners! 🚀

Free resources for learning Data Structures & Algorithms
💡
🤝
Compiled a list of free resources that helped me prepare for technical interviews:
**Video Courses:**
- Abdul Bari's DSA playlist on YouTube
- freeCodeCamp's full course
- MIT OpenCourseWare
**Practice Platforms:**
- LeetCode (start with Easy problems)
- HackerRank
- Codeforces
**Books (Free PDFs):**
- Introduction to Algorithms (CLRS) - Classic!
- Grokking Algorithms - Beginner friendly
**Tips:**
1. Consistency beats intensity - 1 hour daily is better than 10 hours on weekends
2. Don't just watch - code along
3. Explain solutions out loud (rubber duck debugging)
