Enumerables

An enumerable is an object that may be enumerated. "Enumerated" means to count off the members of a set/collection/category one by one (usually in order, usually by name).

"Enumerable" is Ruby's way of saying that we can access each element in a collection, one at a time. Enumerable is a mixin in the Array class and it provides several enumerators such as each, map, select and many more. Find all enumerables and enumerators in the Ruby docs.

Ruby has a tons of enumerables which means that if we pick the right enumerable for the job, our implementation will be very clean and easy to read.

This week we are going to be writing enumerables from scratch. The groups are only allowed to use each, until loops, while loops and for loops.

//------------------------------------------------------------- Split the string on new lines

var text = "What are you talking about?"
split(text);
// #=> ["What", "are", "you", "talking", "about?"]

//------------------------------------------------------------- Reverse the order of the words 

var text = "What are you talking about?"
reverseOrder(text);
