Getting Started with React Hooks

React Hooks revolutionized how React components are written by enabling function components to use state and lifecycle features without classes. Introduced in React 16.8, Hooks provide a cleaner, simpler API that has become the standard approach to React development.

What Are React Hooks? Hooks are special functions whose names start with "use" that allow you to "hook into" React’s state and lifecycle features from functional components. Before Hooks, state and side effects were only possible in class components. Hooks enable these features inside functions, making code more reusable and easier to maintain.

useState Hook The useState hook allows you to add state to function components. It returns an array with the current state value and a function to update it. You provide the initial state as an argument.
