- Q2. If the object is defined with "const" keyword, then in future can it be modified?
- Ans.
No, if an object is defined with 'const' keyword, it cannot be modified in the future.
Objects defined with 'const' keyword are read-only and cannot be reassigned.
Properties of a 'const' object can still be modified, but the object itself cannot be reassigned.
Example: const obj = { key: 'value' }; obj.key = 'new value'; // Valid, but obj = { newKey: 'newValue' }; // Invalid
