On a daily basis you will most likely use your IDE to debug code. However, early on in the course we won't be using the IDE so it's good to know a few things about how to debug your code during the early exercises.
Use pry-debug to stop at will within your code to see what's going on and inspect the environment.
Note: If you have done so already, you will need to install pry-debug and pry-doc by running:
gem install pry-byebug pry-doc
Using the pry-debug in debug_me.rb
- Find out what order the people have been shuffled into before they are printed to screen
- Look inside one of the objects representing John, David or Matz. Can you find the attribute that holds the data?
- What’s the name of it?
- What’s the class of that object?
Find three methods within pry and share them with fellow candidates. Find useful use cases for your findings.
