In this course, you will learn to build a fully-functional application with Rails Webpacker, Webpack, and TypeScript.

To kick things off, you’ll walk through the basics of getting Rails set up to use Webpacker which will serve JavaScript and CSS to the browser. You’ll then get acquainted with Stimulus and React which will help with creating richer interactions.

In the latter half, you’ll work with TypeScript and set up communication between a server. Beyond that, you’ll work through managing state in your Stimulus code, as well as how to test and troubleshoot your application.

By the end of this course, you will be well equipped to create larger, more complex applications that make use of modern tools.

Modern Front-end Development for Rails

If you’ve looked at the schedule page in your browser, you'll see a button next to each day in the schedule labeled “Hide.” Clicking on it does nothing---yet. 
## Toggling the state with TypeScript

If you've looked at the markup for that page in `app/views/schedule/show.html.erb`, you'll see an `each` loop for each day in the schedule. A few lines into that loop, you’ll see a button with the "Hide" text. I've marked up the appropriate DOM elements with some CSS classes that we'll use in the TypeScript code:
