Custom Hooks: Package Component Logic for Reuse
A custom hook packages stateful logic (like useState and useEffect) into a reusable function. Use one when multiple components need the same logic, like tracking online status for a status bar and a save button. Footgun: Names must start with `use`.
Think of a custom hook as creating your own `useState` for a specific purpose. It lets you extract stateful logic into a reusable function, avoiding copy-pasting code between components. This is ideal when multiple components need the same dynamic behavior, like a `useOnlineStatus` hook providing a boolean to both a status bar and a save button. The main footgun: Forgetting that hook names must start with `use` and can only be called at the top level of components or other hooks.
