We want to write a dog class which will do the following:
instances should have a name property which is set when the instance is created.
have an instance method called bark which returns a string formatted as "${this.name} is barking"
have an instance method chainChaseTail which takes a number and calls the helper method chaseTail that number of times. When given an argument that is not a number, chainChaseTail should throw a TypeError.
a class method cleanPaws which takes an array of dogs and returns an array where each element of the array is a string formatted as I cleaned "${this.name}'s paws
