When using the makeNoise method in the dog object, why is "this.noise" used?

Using "this.noise" within the makeNoise method serves the purpose of retrieving the noise property that belongs specifically to the dog object. In JavaScript, the keyword "this" refers to the current instance of the object calling the method. Hence, when makeNoise is invoked on a dog object, "this.noise" allows access to the noise property that has been set on that particular instance. This ensures that the specific value relevant to the dog object, rather than any potentially global or external variables, is accessed.

In object-oriented programming, accessing properties using "this" helps in distinguishing instance variables from local or global variables and contributes to maintaining the integrity of the object's state. In this case, it effectively encapsulates the unique characteristics of each dog object.
