Verifying whether the stack is empty and its size

The count property also works as the size of the stack. So, for the size method, we can simply return the count property:

size() {  return this.count;}

And to verify whether the stack is empty, we can compare if the count value is 0 as follows:

isEmpty() {  return this.count === 0;}
