&gt; I wish all these alt-JS-haskellish language authors (of PureScript, Elm, Roy, etc.) would just work on making GHCJS better.<p>All three of those have very different goals and trade-offs from GHCJS.<p>I agree that it would be nice to share more work&#x2F;knowledge though. One of the nice things about AltJS is that several languages can coexist in the same codebase.
