You will build reliable web applications with a functional language designed for the frontend, static types, a clear architecture, and a development experience focused on preventing runtime errors.

Elm is a functional language for building robust web interfaces. Its type system, model-update-view architecture, and compiler messages make it an excellent tool for learning how to design predictable frontend applications.

In this training you will learn how to model state, events, and data flows in a web application using the Elm architecture. You will also learn how to integrate Elm with HTTP services, JSON, and existing applications while keeping the code easy to understand, test, and evolve.
