๐Ÿ“Œ What Youโ€™ll Learn in This Video
๐Ÿ“Œ๐Ÿ“ŒWhat is Jetpack Compose?
Jetpack Compose is Androidโ€™s modern UI toolkit designed to simplify and accelerate UI development. It replaces the traditional XML-based UI with a declarative programming approach, similar to React or SwiftUI. Compose allows you to create UI components using Kotlin code, making the UI more flexible, testable, and maintainable.

๐Ÿš€๐Ÿš€Key Features of Jetpack Compose:
Declarative UI: Define UI in Kotlin code instead of XML.
Composable Functions: UI components are built using reusable functions.
State Management: Easily manage and update UI with state changes.
Interoperability: Works with existing Android Views and XML layouts.
Material Design Integration: Built-in support for Material Design components.

๐Ÿš€๐Ÿš€Creating Your First Jetpack Compose App
Step 1: Set Up Your Project
Open Android Studio (latest version recommended).
Create a new project and select "Empty Compose Activity".
Name your app and select Kotlin as the language.
Click Finish, and Android Studio will generate a Compose-based project.

Breakdown of the Code
setContent {} โ†’ Sets the UI content of the activity using Compose.
@Composable โ†’ Marks a function as a composable UI function.
Greeting(name: String) โ†’ A composable function that displays a text.
@Preview โ†’ Enables previewing the composable UI in Android Studio.

๐Ÿ”ด1. Composable Functions (@Composable)
A function annotated with @Composable can define UI elements.
๐Ÿ”ด2. Preview (@Preview)
Allows UI previews in Android Studio without running the app.
