JavaScript, often abbreviated as JS, is a programming language that conforms to the ECMAScript specification. JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions.
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.
