Elm is nice. Really really nice. It make it very intuitive and straightforward to write well architectured front end code. The compiler tells you straight away when something is wrong. I have recently started playing with Bucklescript and am really loving it. There is bucklescript-tea which is a port of the Elm architecture to OCaml. So not only do you get the goodness from Elm - intuitively well architectured applications, but you can do it in a language that can be used everywhere - not just on the server. Another worth mentioning is Typescript. Having discovered the joy of types through Elm and Bucklescript it was a real pain having to go back to maintain a fairly large javascript code base. My initial thought was to rewrite the whole thing in OCaml, but that would take months if not years. Instead I have started moving it across to Typescript. No code needs rewriting, I can just slowly one file at a time start adding typing information in. I have found a lot of subtle bugs and bugs I knew existed but was tearing my hair out about just easily presented themselves via compiler messages. I will never go back to raw javascript again.
