Javascript object methods 👇

// 1. Object.keys()

let sampleObject = { name: 'John', age: 30, city: 'New York' };
console.log(Object.keys(sampleObject));

// 2. Object.values()

let sampleObject = { name: 'John', age: 30, city: 'New York' };
console.log(Object.values(sampleObject));

// 3. Object.entries()

let sampleObject = { name: 'John', age: 30, city: 'New York' };
console.log(Object.entries(sampleObject));

// 4. Object.assign()

let obj1 = { a: 1, b: 2 };
let obj2 = { b: 4, c: 5 };
let mergedObject = Object.assign({}, obj1, obj2);
console.log(mergedObject);

// 5. Object.freeze()

let sampleObject = { name: 'John', age: 30 };
Object.freeze(sampleObject);
// Attempting to modify a frozen object will not work
