09/07/2020, 4:37 AMHey. What is a RecomposeScope mentioned in the following paragraph (Sorry it sounds like a TOEFL question! lol)?
MutableState: A mutable value holder where reads to the value property during the execution of a Composable function, the current RecomposeScope will be subscribed to changes of that value. When the value property is written to and changed, a recomposition of any subscribed RecomposeScopes will be scheduled. If value is written to with the same value, no recompositions will be scheduled.

09/07/2020, 5:07 AMA recompose scope is the actual restarting block of a composable. For example, a composable function adds a recompose scope, and the item block to an lazy column adds a recompose scope.
The "Thinking in Compose" page gets into this a bit when explaining how compose skips as much as possible: https://developer.android.com/jetpack/compose/mental-model#skips

{}s
