From just displaying data → actually managing it.
Built a CRUD app with Local Storage today.
• Create
• Read
• Update
• Delete
Big win: Data persists even after refresh.
This made the app feel real.

Explored React Hook Form today and realized how much simpler form handling can be.
Used:
• useForm
• register
• handleSubmit
• reset
Less boilerplate, fewer re-renders, cleaner code.
Step by step, getting better at React.

One of the hardest parts of coding:
Knowing whether the problem is in your logic
or in one missing bracket.
Day 13 of #21DaysChallenge 🚀
Built a Product Card UI using React + Vite today.
Used reusable components, passed data with props, and structured the UI like a real React app.
Small project. Stronger React fundamentals.
