This course shows you how to build front-end web applications with plain JavaScript without using any (third-party) framework or library. It follows a "learning by doing" approach, which means that you don't have to read lots of text about the intricacies of JavaScript. Instead, you’ll focus on the essential parts of JavaScript and read only the minimum needed to start coding your first app. Learning from the examples provided in the course can quickly improve your understanding of basic concepts and techniques. By working your way through the code of these example apps and using it as a starting point for your projects, you’ll learn best practices and experience the joy of building something that really works and that you fully understand.
