Web and Mobile Application
The MERN stack is a popular, JavaScript-based technology stack for building fast, full-stack web and Mobile applications. It consists of MongoDB (NoSQL database), Express.js (backend framework), React.js (frontend library) and Node.js (runtime environment). This unified technology enables efficient, scalable development from frontend to backend. React Native is a separate framework that extends React's capabilities to mobile development, allowing for native iOS and Android apps to be built using JavaScript.
Fast Backend Development
The backend in a MERN application is often referred to as the "application layer" and is built entirely using JavaScript technologies.The backend of a MERN application serves several critical functions, Data Management,Authentication and Authorization,Business Logic and API Endpoints. The main advantage of using the MERN stack for the backend is the use of a single programming language (JavaScript) across the entire stack. This reduces complexity, speeds up development time.
React Native
React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug. Build encapsulated components that manage their state, then compose them to make complex UIs. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app. Reuse code across iOS, Android, and other platforms.
