Describe the state hoisting pattern in Compose
Tests your grasp of unidirectional data flow. Explain state hoisting is moving state up to make composables stateless. This enables reusability, easier testing, and a single source of truth. A red flag is just describing the mechanics without the benefits.
This tests your understanding of unidirectional data flow and building maintainable Compose UIs. A great answer defines state hoisting as moving state up to a composable's caller, making the child stateless. The child then accepts state as a parameter and communicates changes via callbacks (the `(value, onValueChange)` pattern). This yields major benefits: reusability, simplified testing, and a single source of truth. A red flag is failing to explain the callback mechanism or the 'why' behind the pattern.
