ReactJS

React (also known as React.js or ReactJS) is an open-source JavaScript library which is utilized for structured, intuitive and dynamic UI for websites and versatile applications explicitly for creating single page applications where information reflects continuously. As of now, it is one of the most well-known front-end JavaScript libraries in the market. It manages View in the MVC (Model – View – Controller).

In ReactJS, everything is in the form of components. These components are integrated together to build one bigger and dynamic application. The biggest advantage of using components is that you can change any component at any point in time without affecting the rest of the applications. This feature is most effective when implemented with large-scale and real-time applications where data changes frequently. ReactJS automatically updates the specific component whose data needs to be added or updated. This reduces the overhead of the browser to reload the whole application and only change parts of the application.

ReactJS was created by Jordan Walke and is now developed and maintained by Facebook and a community of developers. It allows developers to create complex View layers for web-applications. It’s characterised by uni-directional data flow, component-based architecture and differential updates via Virtual DOM. React is usually combined with libraries such as Redux to develop large applications.
