MEAN Stack Tutorial

📚 151 Lessons

The MEAN Stack (MongoDB, Express.js, Angular, Node.js) is a complete JavaScript-based framework for building dynamic, scalable web applications. Before starting this course, you should have a strong understanding of HTML5, CSS3, and JavaScript (ES6+), including concepts like DOM manipulation, event handling, promises, and async/await.Familiarity with Angular fundamentals such as components, modules, and data binding will give you a strong advantage. You should also understand client-server architecture, REST APIs, and HTTP methods. Basic experience with Git & GitHub and command-line tools is highly recommended. To master MEAN Stack, follow a hands-on, project-based learning approach.
