Day-4 React with Me

On day 4 I dived deep into hooks and discovered 3 new hooks which will help me making my next mini project called a password generator.

useEffect, useRef, and useCallback are three such hooks that play crucial roles in managing state and interactions within React components.

The useEffect hook is used to perform side effects in functional components. Side effects can include data fetching, subscriptions, or manually changing the DOM. It is similar to componentDidMount, componentDidUpdate, and componentWillUnmount in class components.

The useRef hook creates a mutable reference object whose .current property can hold a value. This value persists across renders and does not trigger a re-render when it's updated.

The useCallback hook returns a memoized callback function. It is useful when passing callbacks to optimized child components that rely on reference equality to prevent unnecessary renders.
