The MEAN stack has become a popular choice for web developers seeking a full-stack JavaScript solution. Comprising MongoDB, Express.js, AngularJS (or Angular), and Node.js, the MEAN stack offers a seamless development experience from frontend to backend. MongoDB, a NoSQL database, provides flexibility and scalability in data storage, while Express.js simplifies server-side development with its minimalist framework. AngularJS (or Angular) facilitates dynamic and interactive frontend development with its powerful MVC architecture and two-way data binding. Node.js powers the backend with its event-driven, non-blocking I/O model, enabling high-performance and scalable web applications. Together, these technologies form a cohesive ecosystem that enables developers to build robust, feature-rich web applications efficiently.
