Learn the benefits of Elm and learn why it has the reputation for never crashing. In this course, you'll build an Elm application from start to finish using elm-package to access Elm's package ecosystem, write tests with elm-test, work with third-party JavaScript libraries from Elm using JavaScript Interop, and much more! Throughout the course, Richard discusses tips and tricks for getting the most out of the language. This course uses the latest 0.19 version of Elm.
