What are React Hooks and how do they work?

React Hooks are functions that let you use state and other React features without writing a class. They allow you to manage state and lifecycle methods in functional components.

Can you explain the useState hook?

Sure! The useState hook lets you add state to your functional components. You call it with the initial state and it returns an array with the current state and a function to update it.

How do I use the useEffect hook?

The useEffect hook lets you perform side effects in your components. You can use it to fetch data, subscribe to events, or manually change the DOM. It runs after the render and can be controlled with dependencies.

What are some common pitfalls when using hooks?

Common pitfalls include forgetting to include dependencies in useEffect, using hooks conditionally, and not following the rules of hooks.
