Android Jetpack- Composable functions

Jetpack Compose is built around composable functions. These functions

let you define your app's UI programmatically by describing how it

should look and providing data dependencies, rather than 

focusing on the process of the UI's construction (initializing an 

element, attaching it to a parent, etc.).

To create a composable function, just add the @Composable annotation

to the function name.

Enjoy Coding.... :)
