GHCJS

Running "Hello World!" with Node.js

ghcjs can be invoked with the same command line arguments as ghc. The generated programs can be run directly from the shell with Node.js and SpiderMonkey jsshell. for example:

$ ghcjs -o helloWorld helloWorld.hs
$ node helloWorld.jsexe/all.js
Hello world!
