 // c) What does Object.entries return? Why is it needed in this program?
-
+//object.entries takes an objecet and returns an array of its key-value pairs.
 // d) Explain why the current return value is different from the target output
-
+//because we use .key notation we are setting a property named "key" on our Object.
 // e) Fix the implementation of invert (and write tests to prove it's fixed!)
