React Hooks: A Deep Dive into the 5 Most Used Hooks

React hooks were introduced in React 16.8 to enable functional components to manage state, side effects, context, and more, without the need for class components. Hooks are simple JavaScript functions that can interact with the component lifecycle and React features like state and context. They improve the reusability and readability of your code by allowing logic to be encapsulated in functions instead of classes.

Why Use React Hooks?

Before hooks, React required the use of class components for handling state, lifecycle methods, and other advanced features. With hooks, these features are available in functional components, making your code more concise and easier to manage. Hooks also make it possible to share logic across components by creating custom hooks.

1. useState

The useState hook allows you to add state to functional components. It returns an array containing two elements: the current state value and a function that allows you to update that state.

Use Case: Managing dynamic values like counters, input fields, toggles, or any piece of state that changes during the component's lifecycle.

2. useEffect

The useEffect hook is used to perform side effects in a functional component. This could involve tasks like data fetching, subscriptions, or manually changing the DOM. useEffect runs after every render, and you can control when it should run by specifying dependencies.

Use Case: Fetching data from an API, updating the document title, or handling cleanup tasks such as unsubscribing from services when a component unmounts.

3. useContext

The useContext hook allows you to consume values from a React context without needing to prop-drill. This hook makes it easier to access global data like themes, language preferences, or user authentication status.

Use Case: Accessing shared data across your component tree without having to pass props manually through each level.

4. useRef

The useRef hook is used to persist values across renders without causing a re-render. It can be used for accessing and interacting with DOM elements directly or for storing mutable values that should not trigger re-renders when updated.

Use Case: Storing a reference to a DOM element, accessing previous values, or managing mutable data that does not affect the component rendering.

5. useCallback

The useCallback hook is used to memoize functions. This ensures that a function is not recreated on every render unless its dependencies change. It's particularly useful when passing callbacks to child components or using them in useEffect dependencies.

Use Case: Passing functions to child components without causing unnecessary re-renders, or optimizing performance in lists and grids by memoizing event handlers.
