Report

As a team, answer a subset of the questions submitted during the hackathon. But instead of using Tableau, you will need to write Javascript/Lodash code to derive your answers. Similar to before, each team member is responsible for one question. But everyone should work together to come up with a good solution. Your answer should consist of Lodash code and a brief writeup. Utilize _.map, _.filter, _.group ...etc. Do not se any for loop.

This time, the data is not already prepared for you in a nice JSON format. You will need to do it on your own, replacing the placeholder birdstrike.json with real data.
