Q2. Does a const variable make the value immutable in JavaScript?
Ans. 
No, const does not make the value immutable.
• const only makes the variable itself immutable, not the value it holds.

• For objects and arrays, const prevents reassignment but allows mutation of properties or elements.

• To make a value truly immutable, you can use Object.freeze() or other techniques.
