Since numLegs will probably have the same value for all instances of Bird, you essentially have a duplicated variable numLegs inside each Bird instance.
This may not be an issue when there are only two instances, but imagine if there are millions of instances. That would be a lot of duplicated variables.
-A better way is to use Bird’s prototype. The prototype is an object that is shared among ALL instances of Bird. Here's how to add numLegs to the Bird prototype:
