Word has just come from the higher-ups, and you're in charge of building out a domain that keeps track of weightlifters and the gyms they lift at. Yes gyms. Everyone knows you need a weekday gym and a weekend gym. And one for when you're traveling, and one that you go to just to show off. Oh, and that one with a really great steam room. Gotta love the steam room.
Your goal is to build out all of the methods listed in the deliverables. Do your best to follow Ruby best practices. For example, use higher-level array methods such as map, select, and find when appropriate in place of each.
We've provided you with a console that you can use to test your code. To enter a console session, run ruby tools/console.rb from the command line. You'll be able to test out the methods that you write here. Take a look at that file to see how you can pre-define variables and create object instances, rather than manually doing it in every single console session.
There are no tests! You will need to test your code on your own!!
Troubleshooting: If ruby tools/console.rb does not work, try running bundle install in your terminal.
Here's what we need to be able to do.
