Get started with essential programming language to create interactive websites

JavaScript is known as the "language that powers the web" and was designed to add a level of interactivity to any web page. It is one of the most important programming languages along with HTML and CSS.

This is an introductory course to JavaScript, starting with the basics—syntax and variables—through to concepts such as conditionals, arrays, loops, and events, using a memory game which you build on step by step following the guidance of Javier Usobiaga, web designer and founder of Swwweet studio with more than a decade's experience in the field.

If this is your first crack at web design, it would be a good idea to take Javier Usobiaga's course Introduction to Responsive Web Development with HTML and CSS .
before starting this one.

Web Designer

Javier Usobiaga has been a web designer and front-end developer for over a decade and is cofounder of Swwweet studio alongside Marta Armada.

He also enjoys his role teaching web design workshops and at prestigious schools like Elisava and IDEP.

Javier understands the web in its totality, not only how beautiful it can be on screen, but also how user-friendly it is across all devices and in different contexts.

In his own words, "how fast a page loads and responds is every bit as important as the aesthetic, and something that is often overlooked in our line of work."
