"rxJs". Ok. But why? Why suffer?

Cause it's awesome.

@spongessuck how, and why?

Because it lets you collect a stream of data asynchronously and use array-like functions to effect it, lets you self-contain the source of that asynchronous data, lets you use a really nice pub/sub pattern, lets you use pure functions for event handling, and lets you use the proposed js observables API today, among other things.
