The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

//Drop-in replacement for PHP's SoapClient class supporting connect and response/transfer timeout and authentication
//Usage: Exactly as PHP's SoapClient class, except that some new options are available:
//  timeout         The response/transfer timeout in milliseconds; 0 == default SoapClient / CURL timeout
//  connecttimeout  The connection timeout; 0 == default SoapClient / CURL timeout
//  sslverifypeer   FALSE to stop SoapClient from verifying the peer's certificate
//  sslversion      The SSL version (2 or 3) to use. By default PHP will try to determine this itself, although in some cases this must be set manually
//  sslverifyhost   1 to check the existence of a common name in the SSL peer certificate. 2 to check the existence of a common name and also verify that
