Problem

I'm given a long method (seen below) with two different teams and a number of stats for each player. I needed to come up with different methods to answer a few questions.

1. Build a method, num_points_scored that takes in an argument of a player's name and returns the number of points scored for that player.

2. Build a method, shoe_size, that takes in an argument of a player's name and returns the shoe size for that player.

3. Build a method, team_colors, that takes in an argument of the team name and returns an array of that teams colors.

4. Build a method, team_names, that operates on the game hash to return an array of the team names.

5. Build a method, player_numbers, that takes in an argument of a team name and returns an array of the jersey number's for that team.

6. Build a method, player_stats, that takes in an argument of a player's name and returns a hash of that player's stats.

What I Learned

This lab was a lot easier for me to understand, was more fun and I learned a lot more than the Green Grocer Lab I did last week.

Article No Longer Available

1. How to accept an argument and return a string from inside a nested hash or array.

2. How to use the .map enumerable to create a new array from a nested hash or array.

3. And pretty much anything that accepts an argument and returns any line inside hashes.
