React
React is a popular and widely used JavaScript library for building user interfaces, especially for web
applications. Developed and maintained by Facebook, React is an open-source library that allows developers
to create interactive and dynamic UI components efficiently. React follows the concept of a
component-based architecture, making it easy to manage and reuse UI elements, resulting in a more
structured and maintainable codebase.
React breaks the UI into reusable components, each responsible for its own state and rendering. This
promotes code reusability and modularity, making it easier to develop, maintain, and test applications.
React uses a virtual representation of the actual DOM. When changes occur in the data or state

React efficiently updates only the necessary parts of the real DOM, reducing the number of actual DOM
manipulations and improving application performance.
With React's declarative approach, developers describe how the UI should look based on the data and state,
rather than directly manipulating the DOM. This makes the code more predictable and easier to reason about.
React enforces a unidirectional data flow, where data changes flow from parent components to child components.
This ensures better control over data, reducing the risk of unexpected side effects and making the code more
maintainable.
React has a vast ecosystem of libraries and tools, such as React Router for routing, Redux for state
management, and Axios for handling HTTP requests.
