My #collect

Objectives

1. Build a method that yields members of a collection to a block.
2. Control the return value of a method that uses yield such that it returns a new collection.

Instructions

You'll be writing your code in lib/my_collect.rb.

Let's say we are writing an app to help teachers manage their students. Our teacher has a list of students:

["Tim Jones", "Tom Smith", "Jim Campagno"]

The list includes the first and last name of each student, but our teacher needs to collect a list of just their first names.

You are writing a method that behaves just like the real #collect method. It should take in an argument of a collection, iterate over that collection using a while loop, and execute the code in the block you call it with for each element in the collection (use the yield keyword). It should return the modified collection.

So, if our teacher uses #my_collect to collect the first name of his students, it should work like this:

array = ["Tim Jones", "Tom Smith", "Jim Campagno"]
my_collect(array) do |name|
  name.split(" ").first
end

Should return:

["Tim", "Tom", "Jim"]

Make sure to run bundle install before running your tests.
