Assignment Submission: Ride Share

Congratulations! You're submitting your assignment. Please reflect on the assignment with these questions.

Reflection

Question	Answer
What did your data structure look like at first? Did this structure evolve over time? Why?	At first, the third layer of my data structure had a hash for each ride, but I noticed that multiple rides occurred on the same day for DR0001, so I included an array as the value for the keys of cost, rider_id, and rating to represent those characteristics of a ride in an element.
What was your strategy for going through the data structure and gathering information?	My strategy was calling on each element of a layer in the terminal and going through an example with one ride on paper.
What was an example of something that was necessary to store in a variable? Why was it necessary, useful, or helpful?	Storing the number of rides, earnings, and average rating for each driver into a variable was useful because I used that data structure to summarize the data using a method.
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 the .each iterator throughout my code and the .map iterator in line 120.
Were some calculations easier than others? Why?	Summarizing the data was harder than aggregating it because I took time to think about how I wanted to pull and organize a subset of the data.

Major Learning Goals/Code Review

Criteria	yes/no, and optionally any details/lines of code to reference
Correctly creates, reads, and modifies variables	✔️
Correctly creates and accesses arrays	✔️
Correctly creates and accesses hashes	✔️
Reasonably organizes large amounts of related data into nested arrays and hashes	✔️
Correctly iterates through a nested data structure using loops and/or Enumerable methods	✔️
Reasonably organizes small pieces of code into methods, and calls/invokes those methods	✔️

Functional Requirements

Functional Requirement	yes/no
To the terminal, the program outputs the correct number of rides each driver has given	✔️
... outputs the total amount of money each driver has made	✔️
... outputs the average rating for each driver	✔️
... outputs which driver made the most money	✔️
... outputs which driver has the highest average rating	✔️

Overall Feedback

Great work on this assignment! Your code is readable, logical, and it is clear that the learning goals around working with nested data structure were met. It is particularly noteable that you used one main loop to calculate all the relevant driver statistis. I've left a few inline comments for you to review. One additional thought to consider is encapsulating some of your functionality into a method, though it is not necessary with this program since the functionality is not used more than once. Keep up the hard work!

Overall Feedback	Criteria	yes/no
Green (Meets/Exceeds Standards)	4+ in Code Review && 3+ in Functional Requirements	✔️
Yellow (Approaches Standards)	2-3 in Code Review && 2+ in Functional Requirements
Red (Not at Standard)	0,1 in Code Review or 0,1 in Functional Reqs, or assignment is breaking/doesn’t run with less than 5 minutes of debugging

Great work formatting this data structure for readability.

This is very clear! You could consider using the .reduce enumerable for these operations.

Consider giving nested_hash a more meaningful name
