What is the purpose of `remember` in Jetpack Compose?
This tests your grasp of Compose's recomposition lifecycle. A good answer explains `remember` caches an object across recompositions, preventing state loss. It's used with `mutableStateOf` to hold the same state instance.
This tests your understanding of Compose's core lifecycle: functions are stateless and re-run often. A great answer explains that `remember` stores an object in the Composition's memory, preventing it from being re-initialized on every recomposition. When used with `mutableStateOf`, it ensures you're always referencing the same observable state holder, allowing state changes to persist and trigger UI updates correctly. A common red flag is confusing `remember` (survives recomposition) with `rememberSaveable` (survives configuration changes).
