Welcome to Day 8 of the React JS Full Course.
In this video, we learn one of the most important and commonly used React hooks — useEffect.
The useEffect hook is used to handle side effects in React functional components. Side effects include tasks such as fetching data from an API, running code when a component loads, updating the document title, handling timers, and managing subscriptions.
This lesson explains useEffect from scratch, including how the dependency array works, how useEffect behaves on component mount and update, and how cleanup functions work. Everything is explained with practical examples so beginners can clearly understand and apply the concept in real projects.#reactjs
