Welcome to this JavaScript course.
JavaScript is ubiquitous on the World Wide Web. You can use JavaScript to make your Web pages more interactive, so that they react to a viewer's actions, and to give your Web pages some special visual effects.
JavaScript allows you to add additional features that a static HTML page can't provide without some script code.
The JavaScript lessons of this course are free and a good start for beginners, they offer the necessary elements to learn the JavaScript programming language and working with JS code.
