When you instantiate a variable using mutableStateOf() , Compose wraps that object inside a SnapshotState . val counter = remember mutableStateOf(0) Use code with caution.

Jetpack Compose has completely revolutionized Android development, moving the ecosystem away from imperative XML layouts and into a modern, declarative world. However, truly mastering Compose requires moving past basic syntax and understanding its underlying architecture. When you instantiate a variable using mutableStateOf() ,
If a Composable function receives only parameters, and none of those parameters have changed since the last frame, the function is marked as Skippable . The runtime skips executing the block entirely, dramatically saving CPU cycles.
This component maps the logical tree to physical UI elements.
The main thread typically operates on the Global Snapshot. If you absolutely need an offline reference, —use

Types that might mutate without notifying Compose (e.g., standard collections like List , mutable data models). Composables receiving unstable types can never be skipped and must always re-run. 6. Optimization Strategies for Production
