What is the `Object.freeze` method in JavaScript?

Description : `Object.freeze` prevents modifications to an object.

Answer :

`Object.freeze` is used to make an object immutable by preventing new properties from being added, existing properties from being removed or altered, and marking all properties as read-only. It effectively locks the object from any modifications. 

const obj = { a: 1 };
Object.freeze(obj);
obj.a = 2;
console.log(obj.a); // 1
