The MEAN stack is a collection of JavaScript-based technologies used to develop web applications. The acronym “MEAN” stands for MongoDB, Express.js, Angular, and Node.js. Each component in the MEAN stack brings its own set of functionalities and advantages, allowing developers to build robust and scalable applications entirely with JavaScript.
- MongoDB: NoSQL database, JSON-like format, scalable, high performance.
- Express.js: Minimalist web framework for Node.js, simplifies server-side tasks.
- Angular: Front-end framework by Google, follows MVC, and enables dynamic SPAs.
- Node.js: Server-side JavaScript runtime, event-driven, high performance.
