Class: Hash (Ruby 2.1.4)
A Hash is a dictionary-like collection of unique keys and their values. Also called associative arrays, they are similar to Arrays, but where an Array uses integers as its index, a Hash allows you to use any object type. Hashes enumerate their values in the order that the corresponding keys were inserted. A Hash can be easily created by using its implicit form: grades = { "Jane Doe" => 10, "Jim Do
Class: Range (Ruby 2.1.4)

Ranges constructed using .. run from the beginning to the end inclusively. Those created using ... exclude the end value. When used as an iterator, ranges return each value in the sequence. (-1..-5).to_a #=> [] (-5..-1).to_a #=> [-5, -4, -3, -2, -1
Class: Thread (Ruby 2.1.4)
Threads are the Ruby implementation for a concurrent programming model. Programs that require multiple threads of execution are a perfect candidate for Ruby's Thread class. For example, we can create a new thread separate from the main thread's execution using ::new. thr = Thread.new { puts "Whats the big deal" } Then we are able to pause the execution of the main thread and allow our new thread t
