What are const objects in JavaScript?

What are const objects in JavaScript?

In JavaScript, a const object is an object that cannot be reassigned. However, its properties can still be modified.

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

Sure! Here's an example:

const person = { name: 'Alice', age: 25 };
person.age = 26; // This is allowed
console.log(person); // { name: 'Alice', age: 26 }

// person = {}; // This would 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. For example:

const car = { brand: 'Toyota' };
car = { brand: 'Honda' }; // TypeError: Assignment to constant variable.

Are there any limitations to using const objects?

Yes, while you can't reassign a const object, you can still change its properties. Just remember that const only protects the variable binding, not the object itself.
