Recapping the concepts I know.
State
-
setState: sets the state for the next render. - State is private to each instance of a component. If you render the same component in two different places, each will have its own separate state.
- React hooks rely on a fixed call order.
Render and Commit
- A component re-renders if and only if its state or it's parents' state are changed. (Specifically, props has nothing to do with re-renders, unless one uses
memo.)
