In this exercise, you only need to interpret the code. Your answers to the questions are good.
The goal is to be able to distinguish the difference between these two syntax:
obj[key]obj.key
Tests are optional and you could leave the test code here if you want.

Thanks for explaining CJ. I'll keep the tests in a single file for better access.

Completed the latest Sprint 2 exercises, working with JavaScript objects, key-value pairs and loops. Added tests, fixed bugs and improved my understanding of how to work with objects.
Questions
I did not know if I should make a new test file for invert.js file or just write down tests below comments.
