Pros
Pro It's just Haskell
No need to learn any new semantics, it's just a switch to a different compiler.
Pro Flexible FFI
UHC uses a printf-like syntax for its FFI, which is flexible enough to minimize the need for wrapper functions, when, e.g., calling methods on objects. It also supports %*
, for working with functions that take arbitrary parameters, such as concat
.
UHC also has support for wrapper imports and dynamic imports, for passing Haskell functions as callbacks to Javascript, or dealing with curried Javascript functions, respectively.
Cons
Con No support for Language Extensions
No support for things like Arrow Syntax - this is particularly a disadvantage when compared to options like Elm (which was designed around good syntax for Arrowized FRP), if you're looking to do Functional Reactive front-end development.
