> Elm is a young language that has changed its design patterns significantly in the last year or two In the past 2 years there was one big change (0.16 -> 0.17) that said "instead of being best practice, the Elm Architecture is now the only way to do it." [0] Every other release has not meaningfully affected design patterns as far as I can remember. That said, I agree that it's fair to consider "removing alternatives to the best practice" a significant change of design patterns. For for those who had been following different patterns, I know it was a big change. You're also right that Elm is a young language, and there's inherent risk of change that comes along with that. :) > perhaps it is unfair to expect it to be as capable and mature as alternative languages. I don't want to claim Elm is flawless, or for that matter stable and mature—because right now it's none of those things. Sure, it's been battle-tested and proven more than capable, but of course that's not the only factor in choosing a language. I would note that from what I've heard, among functional altJS languages Elm is second in maturity only to ClojureScript. (I base that on conversations I've had with users of CLJS, PureScript, ReasonML, GHCjs, and ScalaJS.) As far as I can tell, the only other "alternative language" that's more mature than Elm is JavaScript itself—or maybe TypeScript, if you count that as a separate language. To be clear, what I do want to claim is that Elm is a strong choice for typical web applications. That's true of small ones, medium-sized ones, and especially big ones. Again, when I make that claim, I'm not saying that everyone should choose Elm for their project. Projects differ, and people have preferences. Elsewhere in this comment thread is someone who preferred ClojureScript, and someone else who preferred PureScript. Great! :D What I'm saying is that nobody should be concerned about whether Elm applications can scale well. They already have scaled well for plenty of projects. There clearly is not some "abstraction wall" that prevents this from happening, and people having personal preferences for other languages' design choices doesn't imply otherwise. :) [0] http://elm-lang.org/blog/farewell-to-frp http://elm-lang.org/blog/farewell-to-frp
