- must not call React Hooks outside of the component function.
- must not call React Hooks inside of if statements.
- must not call React Hooks inside of nested functions.
- Hooks: must be used directly in the root level of the component function.
- Key prop on a component that is not a part of a list: whenever it changes, react will destroy the old component instance and create a new one.
- useRef: use refs for managing values that are stored and managed independently from the component function lifecycle to which they belong.
- Memo: prevents functional components executions that are triggered from the parent component. You might avoid it by clever component structuring.
- useMemo: prevents function execution, only re-executeif one of the dependencies is changed.
- useCallback: used to avoid recreation of a function.
- Prop drilling = passing shared data through multiple components layers even tho most components don't directly need that data (just pass it on to the child component).
- Component composition = one way to solve prop drilling, the middle component act as a wrapper.
- Don't do side effects (async code) inside reducers.
- Thunk: is a function that delays an action until later.
- Index routes: allows you to define the default route that should be loaded if the parent routes path is active.
- useLoaderData: you can access loaded data with help of useLoaderData in any component on the same level or lower level.
- useFetcher: use it if you wanna trigger a loader or an action without actually loading the page, the route to which this action or loader belongs.
