How do I use const with objects in TypeScript?

In TypeScript, using const with objects means that the reference to the object cannot be changed, but the properties of the object can be modified.

Can you give me an example?

Sure! Here's an example:

const person = { name: 'Alice', age: 30 };

// You can modify properties:
person.age = 31;

// But you cannot reassign the object:
person = { name: 'Bob', age: 25 }; // This will cause an error

What happens if I try to reassign the object?

If you try to reassign the object, TypeScript will throw an error saying that you cannot assign to a constant variable.

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.
