I have used Elm for a couple projects recently and the main benefit is it forces you to program in a maintainable and correct fashion. The community is active and tries to find the right patterns to use without compromising these core principles. I think the potential of a language like this for testable UI's could revolutionize and simplify client side development if it gains enough momentum.
