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.

What I like about it is that I am able to solve the challenges in a TDD way working in a environment that I am familiar (my own PC not a browser IDE) and the cherry on the top of the cake is that I have access to code reviews.
