Comprehension Questions

Question	Answer
What did your data structure look like at first? Did this structure evolve over time? Why?	At first it was an array of hashes. It did evolve into a hash with a nested array of hashes. It evolved into this because the questions focused on the drivers and their individual records so grouping the information by driver/driver history seemed like a good way to go.
What was your strategy for going through the data structure and gathering information?	My strategy was using mostly .each loops and then using the .sum and .map enumerables to return some quick calculations.
What was an example of something that was necessary to store in a variable? Why was it necessary, useful, or helpful?	When I used .map for question 4 to return an array of hashes with name: driver and value: $ total earnings - since it is necessary to store that returned value in a variable in order to use it to later.
What kinds of iteration did you use? Did you use .map? If so, when? If not, why, or when would be a good opportunity to use it?	I used each loops, map, and sum. For determining who made the most money, I used map to create a smaller array of hashes that I could then use the max_by to determine which driver made the most $ dough.
Were some calculations easier than others? Why?	I thought that figuring out totals was easy using the sum enumerable since it only required one step, it seemed more straight forward and thus felt easier.

This is mostly easy to read, but be aware, the { can be on it's own line or with the thing it's attached to. usually you'd see this formatted:

all_averages = ride_share.map do |driver, rides|{ 
  name: driver, average: rides.sum do |record|
    ((record[:rating].to_f) / rides.length).round(2)
  end 
}end

Indentation got a bit out of hand here.
