It was designed by Evan Czaplicki as part of writing his thesis on Concurrent FRP for Functional GUIs and evolved into a language to help make making user interfaces better.
Elm's goal is to be the simplest and best language for making web-based user interfaces.
Elm aims to completely eliminate runtime exceptions by combining an aggressively helpful compiler with solid architectural principles.

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.
Once you join the Elm language track, you will receive support and feedback from our team of mentors. Here are the bios of a few of the mentors of this track.
These are a few of the 42 exercises on the Elm track. You can see all the exercises here.
