my-select-dumbo-web-060319's Introduction

my_select

Objectives

  1. Continue to practice using yield and blocks.
  2. Gain a deeper understanding of the common enumerable .select.

Instructions

Now that we've built our own .each and .collect methods, let's build our own .select method! If you don't remember what .select does, review the Ruby docs on it.

Run bundle install first to update or install any gems.

Write your code in lib/my_select.rb. Get the tests to pass.

A few things to think about:

  • What is the return value of yielding a character to a block?
  • How can you ensure your .select method can respond appropriately to being passed an argument of an empty collection?
