React as a UI Runtime — Overreacted - re - render Child // - re - render Child - re - render Parent  - re - render Child The setState calls in components wouldn’t immediately cause a re-render. Instead, React would execute all event handlers first, and then trigger a single re-render batching all of those updates together. If we start with count set to 0 , these would just be three setCount(1) calls. To fix this, setState provides an overload that accepts an “updater” function: c => c + 1 ...

Normally, variables “disappear” when the function exits but state variables are preserved by React. If we wanted to store two different values in state, we would call useState() twice. State variables can hold objects and arrays just fine, so you can still group related data together. However, unlike this.setState in a class, updating a state variable always replaces it instead of merging it. Hooks at a...
