Updating Object Properties with Const

Variables declared with const cannot be reassigned to a new value, but the properties of an object stored in a const variable can still be modified.

const user = { name: 'Alex' };
user.name = 'Sam';
console.log(user.name); // Output: "Sam"

const user = { name: 'Alex' };

Creates a constant reference to an object.

user.name = 'Sam';

Modifies a property inside the object, which is allowed even with const.
