课程概况

This course is part of W3C’s “Front-End Web Developer” Professional Certificate.

This computer science course is an initiation to JavaScript programming and has been designed to help Web developers have an understanding of the basic concepts of the language. This course was developed in partnership between W3C and University Côte d’Azur.

JavaScript lets you add interactive features to your Web sites, including dynamically updated content, controlled multimedia, animated images, and much more.

The main objective of this course is to master JavaScript best practices by means of many interactive examples, some of which are demonstrated in live coding videos.

We’ll use JavaScript within the Web browser. Why JavaScript is worth your time:

HTML5, CSS and JavaScript are the “classic three” for developers and designers;
It allows you to add interactivity to your Web sites;
You can use JavaScript and HTML5 APIs to create custom graphics and animation, and to master multimedia using audio and video players, music and sound effects;
It is powerful, easy to learn, and quick to write;
It has great tools (editors, runtimes, lint tools, browsers, and third party libraries) as well as great online support through plenty of active open source communities.

At the end of the course, we expect that you will be able to read the source code of any JavaScript example found on the Web, learn from it, tweak it, and even – why not? – start contributing to open-source JavaScript projects. This introductory course will make you think like a JavaScript developer.
