Elm is for making Web applications.
Elm aims at the most enjoyable developer experience possible.
Elm has tiny compilation times, small assets and a fast runtime.
Thanks to strict typing, Elm catches potential errors at compilation.
Elm has a dedicated interop mechanism with JavaScript called ports.
Elm is a simple pure functional language, a good gateway for more advanced functional languages.
Every language has its own way of doing things. Elm is no different. Our mentors will help you learn to think like a Elm developer and how to write idiomatic code in Elm. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Elm - they'll help you discover the things you don't know that you don't know.
