Q6. Variable hoisting in js

Q8. Shallow vs deep copy in js
Ans. 
Shallow copy creates a new object but references the same nested objects, while deep copy creates a new object with copies of all nested objects.
• Shallow copy only copies the top-level object, not the nested objects.

• Deep copy creates new copies of all nested objects, ensuring they are independent.

• In JavaScript, shallow copy can be achieved using Object.assign or spread operator, while deep copy can be achieved using JSO
