JavaScript Programming Course

About this course

JavaScript is a core technology of modern web applications. Developers use it to implement client-side logic, respond to user actions and communicate with web services. It is also the foundation for frameworks such as Angular and React.

The JavaScript Programming course teaches developers how to use JavaScript to build interactive behaviour in web pages. You will write code that processes user input, manipulates page content and controls program flow in the browser. The course focuses on the core language features required to develop and maintain browser-based applications.

You should already have some programming experience and a good understanding of HTML before attending this course.
