What is the purpose of using const in JavaScript objects?

Using const in JavaScript means that the variable cannot be reassigned. However, the properties of an object defined with const can still be modified.

Can you give me an example of using const with an object?

Sure! Here's an example:

const person = { name: 'Alice', age: 25 };
person.age = 26; // This is allowed
person = { name: 'Bob' }; // This will throw an error

What happens if I try to reassign a const object?

If you try to reassign a const object, you'll get a TypeError. The reference to the object cannot change, but you can still modify its properties.

Are there any best practices for using const with objects?

Yes! It's best to use const for objects when you want to ensure that the reference remains unchanged, promoting immutability in your code.
