Elm on the frontend is kinda starting to make me feel the same way I feel about Go on the backend. It makes a lot of things really easy and the APIs are very nice. It always seems like a good choice right up until I find a huge wall caused by the intentional omission of some feature or another, and then I'm back to wondering if I actually like it or not.

I wish folks from these languages with great communities and APIs would work more on languages that are more powerful and expressive.
