JavaScript Object Methods

Object.keys(): Get All Keys

```javascript const user = { name: 'John', age: 25, email: 'john@example.com' }; const keys = Object.keys(user); // ['name', 'age', 'email'] ```

Object.values(): Get All Values

```javascript const values = Object.values(user); // ['John', 25, 'john@example.com'] ```

Object.assign(): Copy Objects

```javascript const user = { name: 'John' }; const updated = Object.assign({}, user, { age: 25 }); // { name: 'John', age: 25 } ```

Spread for Objects

```javascript const updated = { ...user, age: 25 }; ```

Key Takeaway

Object methods manipulate objects. Use keys() for keys, values() for values. Use spread for modern copying. Essential for object operations.
