Stimulus is described as "A modest JavaScript framework for the HTML you already have." More specifically, it’s a way to add JavaScript behavior to HTML in a structured and consistent way:

 It doesn’t seek to take over your entire front-end—in fact, it’s not concerned with rendering HTML at all. Instead, it’s designed to augment your HTML with just enough behavior to make it shine.

In this course, students will learn basics of Stimulus by creating web app.

We'll start off by setting up a Stimulus project, use controllers in Stimulus, and set up a build process for a Stimulus app. We'll also get into how to work with state in a Stimulus app.
