raushan-ttn/react-learning ? reverse-engineered prompt

I want this starter React project turned into a simple beginner friendly learning app instead of the default page. Make it feel like something I can open and click through to understand the basics of React, with a clean layout and easy to read code.

A good direction would be a small demo app with a few sections that show common React ideas in a practical way, like reusable components, passing data into components, state updates, conditional rendering, handling a form, rendering a list, and maybe fetching a little sample data from a public API. Keep everything lightweight and polished, not overly fancy.

Please add clear labels, helpful comments, and a nice simple design so it feels like a real mini project I could study. If something needs deciding, choose the most beginner friendly option. Also make sure it runs properly with the normal start command, and add a short README note explaining what each part of the app is meant to teach.
