Good news πŸ“°.
When nesting some Views, like RelativeLayout, you could see some performance issues with the Android View system. Compose doesn’t use multiple measures, so you can nest as deeply as you like without performance suffering.

How Layouts are built ?
The fundamental component of Compose is Composable function. A function emitting Unit (Nothing) that describes a specific area of your UI is referred to as composable function. The function receives some input and produces the content displayed on the screen. Multiple/nested UI elements could be produced using a Composable function. But the total control of displaying the elements is done by us.
