JavaScript Object Methods

Object.keys(): Get All Keys

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

Object.values(): Get All Values

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

Object.assign(): Copy Objects

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

Spread for Objects

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.
