What is difference between deep and shallow object coping in JavaScript?

Some differences are:

• Deep copy means copies all values or properties recursively in the new object whereas shallow copy copies only the reference.
• In a deep copy, changes in the new object don't show in original object whereas, in shallow copy, changes in new objects will reflect in the original object.
• In a deep copy, original objects do not share the same properties with new object whereas, in shallow copy, they do.
