Though with the advent of LLMs it became very easy to spin up alternate backends for it, so it's very much alive outside of JS as well.
it taught me a lot of things - such as simplicity. when I ended up switching to react - redux was easy to pick up cz of elm.
sadly the ecosystem never grew. but oh man elm is nice & the apps were performant.
You won't understand why elm is simple until you actually use elm to the point of internal understanding. I think doing this is much harder nowadays given that most people would likely use an LLM to do most of the coding.
I love Elm, and I love the community, but I feel a little gaslit here.
Also, if you ever had to refactor anything, there is no language in the world that makes it as easy to change things.
Hope to see more releases in the future.
