On the reasoning behind the new course, Treehouse founder Ryan Carson told .net: "jQuery is one of the most popular ways to add interactivity to a website. We think it's important for everyone who's learning how to make websites to learn jQuery." Treehouse jQuery educator Andrew Chalkley added that teaching interactivity was also the "next logical step" in Treehouse's offering, given that it has been working through teaching how to build a site and make it responsive.
In terms of the specifics taught on the course, Chalkley said the bulk of the jQuery core is covered, along with those things that are popular on websites, thereby giving students a strong grounding in essential website interactivity: "For example, form validation exposes students to the various text input events that can really improve user experience. Plug-ins save a lot of time, so designers and developers can focus on what matters to their projects and not get bogged down reinventing the wheel. Maps are an important way to visually communicate locations, and figuring out how to use and customise Google Maps is a great tool to have in your utility belt. The key to all of this is keeping the website responsive. We don't think anyone else is really bearing this in mind in their courses, but we are."
