Overview

This repository was created as a resource for the BE Mod1 Lesson on each. It can be used in conjunction with the Exploring #each slide deck.

Setup

You do not need to fork this repository unless you want a copy in your own Github account. For the purposes of the lesson, you can:

  • Clone this repo

Making it run

This repository has four folders. For the purposes of the lesson, the folder order is as follows:

  • vocabulary
  • warm_up
  • exercises
  • practice

In exercises folder you will see the following files. For the purposes of the lesson, the file order is as follows:

  • warm_up.rb

  • using_each.rb

  • transforming_elements.rb

  • subset.rb

  • create_new.rb

  • In each of the files you will have a collection that you will write code for, implementing the .each method.

  • Below the collection you will see commented out instructions on what you are trying to implement and the questions you will work to answer.

  • These files will not implement tests so you will need to use a p or puts before the variable you want to output to your terminal.

    Example:

    names = ["bob", "linda", "joe", "sally"]
p names

or

names = ["bob", "linda", "joe", "sally"]

names.each do |name|
  puts name
end

  • In your terminal make sure that you cd into the directory that you created and put your cloned repository into. Then cd each.

  • In your terminal you will follow this format to run the file and have it print:

ruby exercises/<name of file you want to run>
