Run npm test in js/ directory. Right now the tests get the same Map object, because the require() always returns a reference to the same object, even though it is called once per test. This is undesirable because it could cause confusing interdependencies between tests.
- Add a new mock element in the dom for the year selector - Modify mock data to reflect the new data format
I want to be able to isolate the map class to test it. The changes here are: - Move the const mapping of data keys to user-facing strings inside a map class function. This also avoids needing to worry about updating the previously cached Map.populationKey and map.groupKey values (now it is updated on demand) - Pass in the year selector to the Map class
- Modify index.js to export the Map class rather than an instance of the Map class - Modify index.html to instantiate a Map now that index.js does not
- Style of district data that does not exist returns stripes - Style of district that is missing data returns stripes - Popup of district with higher count than population shows error

I'm so sorry for the delay in sending this pr. I am planning on writing some more tests this afternoon but thought I'd better send an initial pr over now to hold myself accountable :)
I should have some time to make edits so please feel free to share any feedback.
