🚀 Transforming Mutable Objects to Immutable in JavaScript 🚀

In JavaScript, the ability to control the mutability of objects can be a game-changer. Let's explore three methods to make objects immutable, ensuring they remain unchangeable:

const person = { firstName: "atul", lastName: "bansal"};

🔒 Object.seal 🔒 see code in attached image below
Object.seal(person) allows you to lock an object down, preventing the addition or deletion of properties. However, you can still modify the property values. Take a look

❄️ Object.freeze ❄️ see code in attached image below
Object.freeze(person) takes it a step further by making the object completely immutable. No additions, deletions, or modifications are allowed:

🔐 Object.defineProperty 🔐 see code in attached image below
Another approach is to use Object.defineProperty to set specific properties as non-writable:

These techniques offer flexibility in controlling object mutability in JavaScript, allowing you to design more robust applications. # #JavaScript #ImmutableObjects
