My answer to this has changed quite a bit over the last year. It used to be the case, at least as I saw it, that Elm had a UI focus, and PureScript tried to be a general-purpose language. So it came down to typical expressiveness vs. toolin

> I wish all these alt-JS-haskellish language authors (of PureScript, Elm, Roy, etc.) would just work on making GHCJS better. All three of those have very different goals and trade-offs from GHCJS. I agree that it would be nice to share

I hope you find PureScript has improved considerably since you last looked, but if you have any specific issues, please drop into #purescript IRC and let us know.

There are some PureScript projects that I know of running on Node, although it is admittedly less common. I'm currently working on a framework to build REST services in PureScript, so hopefully the situation will improve shortly.

The largest all-PureScript application I know of is SlamData[0], which takes about 12s for a rebuild, but SlamData uses a _lot_ of modules. For smaller projects it's much less. It's not great, but performance is one of three main

Monad transformers and PureScript's row-based effects are two complementary approaches to the problem of extensible effects. Some effects in PureScript look a lot like the effects provided by certain monad transformers (StateT/ST&

I don't know Alice ML but one advantage of using abstractions like Applicative is that you can write code which is polymorphic in the particular applicative you choose. So, you can mock your concurrent requests using the Identity or Zi

An Applicative functor is a type constructor which lets you lift functions of arbitrary numbers of arguments to functions whose arguments are wrapped with that type constructor. Concretely, if you think about promises in JavaScript, for exa

One thing I find surprisingly effective is that I write a todo list on paper every morning, and check items off as they get done. I keep a longer todo list of personal goals on a Trello board.

Right now, the translation is very direct. My basic rule of thumb is - only perform those optimizations which the user opts into. Some things are standard though, like a few inlining rules and tail call elimination, but the plan is to provi

I can't really comment on source maps in Elm, but the approach in PureScript has been to generate clean, readable JS which is debuggable directly. Source maps are on the roadmap, but not really a priority right now. I haven't hear

I won't argue that Elm does anything other than an exemplary job at #3, but it is worth noting that there are some interesting efforts to build similar functionality in PureScript libraries: https://github.com/paf31&#x2

I tried to change the whitespace rules in the PureScript parser to match Haskell recently (to support explicit braces), and it proved to be very difficult. The "L" function which is defined in the Haskell 98 Report depends heavily
