This Open Educational Resource (OER) is designed for individuals eager to learn full-stack development, focusing on JavaScript, Node.js, and MongoDB. It offers a comprehensive curriculum that takes learners from the basics of programming to developing complete web applications.
The course begins with JavaScript fundamentals, teaching learners how to add interactive features to web pages and create a dynamic user experience. It then advances to server-side development with Node.js, allowing participants to build scalable and efficient web servers. Then, MongoDB is introduced as a flexible, document-oriented database, perfect for accommodating the complex data needs of modern web applications.
The resource is structured to support both beginners and intermediate developers. It includes a mix of resources, including video lectures, lecture notes, source code, and tutorials.
