So, let’s flip a coin: if it’s heads, play a drum, if it’s tails, play a cymbal. Easy. We can emulate a coin flip with our one_in function (introduced in the section on randomness) specifying a probability of 1 in 2: one_in(2). We can then use the result of this to decide between two pieces of code, the code to play the drum and the code to play the cymbal:
loop do
if one_in(2)
sample :drum_heavy_kick
else
sample :drum_cymbal_closed
end

The introduction to Reactive Programming you've been missing

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

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.
