How do I learn components and jsx basics?

Components are reusable UI pieces. Start with the [Quick Start](https://react.dev/learn). # Create Components ```jsx function MyButton() { return I'm a button ; } export default function MyApp() { return ( Welcome ); } ``` # JSX Rules - Capitalize component names. - Self-close tags: ` `. - Wrap siblings: ` ` or `<>... `. # Add Styles Use `className`: ```jsx ``` ```css .avatar { border-radius: 50%; } ```

How do I display data and conditional rendering?

# Embed JS in JSX Use `{}` for expressions: ```jsx const user = { name: 'Alice' }; {user.name} ; ``` # Inline Styles ```jsx ``` # Conditionals ```jsx {isLoggedIn ? : } {showMessage && Message } ``` Practice in your app: Add a user profile with conditional admin panel.

How do I render lists and handle events?
