React Router is a standard library for routing in React applications. It enables the navigation between different views (components) of a React application, allowing you to build a single-page application with multiple "pages" or views. Here's a basic overview of using React Router: Installation: You can install React Router using npm or yarn: or Usage: 1. BrowserRouter: Wrap your application with the `BrowserRouter`. Thi…

React Hooks are functions that allow functional components to use state and lifecycle features that were previously only available in class components. They were introduced in React 16.8 as a way to enable stateful logic in functional components, making them more powerful and reducing the need for class components. Here are some commonly used React Hooks: 1. useState: Allows functional components to have local state. Syntax: `const [st…

In React, both state and props are used to manage data and control the behavior of components, but they serve different purposes and have some key differences. State: 1. Local to the Component: State is a local/internal data storage available only to the component that owns and sets it. It is initialized in the `constructor` method of a class component. 2.
