What is the useState hook?

useState is a React Hook that lets you add state variables to functional components. It returns the current state value and a function to update it.

When should I use useEffect?

The useEffect hook is used to perform side effects in components, such as fetching data from an API, subscribing to events, or manually updating the DOM.

What are React Hooks?

React Hooks are functions that let you 'hook into' React state and lifecycle features from function components without needing to write a class component.

URL Node

State Management.

The URL is the single source of truth for your application's state. Managing it effectively allows users to bookmark specific views, share filtered results, and navigate through complex workflows with ease.

1Understanding Location

The useLocation hook provides a snapshot of the current URL. Unlike a standard string, it breaks the URL down into useful pieces: pathname (the path), search (query parameters), and hash (anchor links). It also includes a key property, which is unique for every individual navigation event, helping React identify when a user returns to a previous page.

2URL as State Store

For filters, search terms, or pagination, the URL is often better than internal React state. By using useSearchParams, you can synchronize your UI with the URL. This ensures that if a user refreshes the page or shares a link, the exact same filters and search results are preserved, creating a much more professional and user-friendly experience.
