Ruby Array, Hash, and Enumerable methods

What is this?

This is a list of methods from Ruby's Array, Hash, and Enumerable that I find useful and have used a lot. It is by no means an complete list so just think of it as a starting point. (BTW, Enumerable is a mixin and not a class but both Array and Hash include it they both have Enumerable methods avaliable to them.)

In preperation for this week and the upcoming week make sure you are understand how to sort and filter each of these data structures. Read the documentation on these methods and play with them in IRB.

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.

	require 'pry-byebug'

	def get_even_numbers_from_zero_to(number)

	numbers = []

	(0..9).each do \|number\|
	numbers << number if (number % 2 == 0)
	end
