Jumping into Jetpack Compose way too early to see what's inside
summary
Jetpack Compose replaces views with composable functions that annotate Kotlin code, run as plain functions and draw directly to a canvas; the system is split into a runtime, a compiler plugin and tooling. The compiler works on Kotlin compiler IR to add caching and grouping hints so repeated list items avoid re-rendering, state APIs (model annotation, memo, effects) remain experimental, and the tooling is usable but fragile and frequently breaks.
