Question

In deep copying we should not have the reference of previous object in our new copy anywhere.manipulsting copy should not affect the original object.

Answer 1

Scroll down and check out "Deep copy with custom function 3" if you don't want to use a library. It's fine for smaller to mid sized arrays and objects but it is a bit slow. If you need to use with large to very large objects or arrays, I would suggest you use #5 library "rfdc".
