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.

	#!/bin/bash
	#
	# Report time to first byte for the provided URL using a cache buster to ensure
	# that we're measuring full cold-cache performance

	while (($#)); do
	echo $1
	curl -so /dev/null -H "Pragma: no-cache" -H "Cache-Control: no-cache" \
	-w "%{http_code}\tPre-Transfer: %{time_pretransfer}\tStart Transfer: %{time_starttransfer}\tTotal: %{time_total}\tSize: %{size_download}\n" \
	"$1?`date +%s`"

	/**
	* Parse query string.
	* ?a=b&c=d to {a: b, c: d}
	* @param {String} (option) queryString
	* @return {Object} query params
	*/
	getQueryParams: function(queryString) {
	var query = (queryString \|\| window.location.search).substring(1); // delete ?
	if (!query) {
	return false;
