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.
Build a method,
num_points_scoredthat takes in an argument of a player's name and returns the number of points scored for that player.Build a method,
shoe_size, that takes in an argument of a player's name and returns the shoe size for that player.Build a method,
team_colors, that takes in an argument of the team name and returns an array of that teams colors.Build a method,
team_names, that operates on the game hash to return an array of the team names.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.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
How to accept an argument and return a string from inside a nested hash or array.
How to use the
.mapenumerable to create a new array from a nested hash or array.And pretty much anything that accepts an argument and returns any line inside hashes.
Final Iteration
