JavaScript Interview Question - What is difference between Shallow Copy and Deep Copy?

JavaScript Interview Question - What is difference between Shallow Copy and Deep Copy? ============================================================ Shallow copy : Shallow copy creates a new object, but it does not create copies of nested objects. Instead, it copies references to the original nested objects. If you modify a nested object in the copied object, the change will be reflected in the original object and vice versa. Deep copy : Deep copy creates a completely independent copy of the original object, including all nested objects. Modifying the nested objects in the copied object does not affect the original object, and vice versa.
