What is React ?

React is an open-source JavaScript library for building user interfaces (UIs). It was developed by Facebook and released in 2013. React is widely used to create interactive and dynamic web applications.

React follows a component-based architecture, where the UI is divided into reusable components. Each component manages its own state and updates the UI based on changes in that state. This approach makes it easier to build complex UIs by composing smaller, reusable components together.

One of the key features of React is its use of a virtual DOM (Document Object Model). The virtual DOM is a lightweight copy of the actual DOM, which is a representation of the web page's structure. React uses the virtual DOM to efficiently update and render only the components that have changed, instead of re-rendering the entire page. This approach improves performance and makes React applications fast and responsive

React can be used to build single-page applications (SPAs) as well as mobile applications using React Native. It has a vast ecosystem of libraries, tools, and community support, making it a popular choice for front-end development.
