What is remember in Compose and how do you use mutableStateOf?
This tests state survival across recompositions. Good answers say remember caches values across recompositions, pairs with mutableStateOf for observable state, and shows a counter. A red flag is mutableStateOf without remember, state resets per recomposition.
This tests your understanding of state survival across recompositions versus plain local variables. A strong answer explains that remember caches a value across recompositions so it is not reinitialized; pairs it with mutableStateOf to create observable state that triggers recomposition when mutated; and provides a minimal code example such as a counter with a button.
