Tell me what makes the angular.copy() method so powerful?
Answer:
It creates a deep copy of the variable.
A deep copy of a variable means it doesn’t point to the same memory reference as that variable. Usually assigning one variable to another creates a “shallow copy”, which makes the two variables point to the same memory reference. Therefore if we change one, the other changes as well
