MEAN, a JavaScript software stack, is becoming the go-to choice for mobile web API development. Its four components – MongoDB, Express.js, Angular.js, and Node.js – offer a full-stack solution for developers. MongoDB is a document database that stores data in flexible, JSON-like documents, enabling developers to work with data in a more intuitive way. Express.js is a web application framework for Node.js, designed for building web applications and APIs. Angular.js is a JavaScript-based open-source front-end web application framework, while Node.js is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code outside of a browser.

MEAN is gaining popularity due to its efficiency, flexibility, and the speed it offers in the development process. It enables developers to use JavaScript on both the client and the server side, reducing the need to switch between languages. It’s also open-source, meaning it’s continually updated and improved by a community of developers. Moreover, it’s highly flexible, allowing developers to test an app on the cloud platform during the development process. Lastly, it’s cost-effective, as it requires fewer developers and less time to build applications.
