React is an open-source, front end, JavaScript library for building user interfaces or UI components. It is maintained by Facebook and a community of individual developers and companies. React can be used as a base in the development of single-page or mobile applications.

JavaScript vs React

React is a framework for building applications using JavaScript. React Native is an entire platform allowing you to build native, cross-platform mobile apps, and React. js is a JavaScript library you use for constructing a high performing UI layer

• React components have reusable codes that make it simple to use and learn.

• React library has JSX (JavaScript XML), which is HTML like syntax, which is processed into JavaScript calls.

• React components are reusable which helps while working on larger scale projects and has their own logic and controls.

• One-way data binding provides better control throughout the application.

• The virtual DOM uses the ReactDOM library which ideally/virtually, represents UI and keeps in the memory and syncs with the real DOM.

• DOM has a smoother and faster performance due to virtual components.
