TameJS

Note Tame is not an attempt to dumb down async programming. It's just a cleaner way to write it. Further, your programs will likely have lower latency; with Tame it's a lot easier to keep parallel calls parallel.

Tame JS doesn't just 'dumb down' async programming in Javascript, it makes it beautiful, simple and incredibly elegant.

The sample code demonstrating parallel dns lookups in Node show just how simple it is.

Definitely one to play with in the future.
