Partial

Partial makes all properties of a type optional, creating a type with the same properties but each marked as optional.
Useful when updating or modifying parts of an object.

interface User {
  id: string;
  name: string;
  age: number;
  email: string;
  password: string;
}

type UpdateUserProps = Partial<Pick<User, 'name' | 'age' | 'email'>>;

function updateUser(updatedProps: UpdateUserProps) {
  // Update user in the database
  console.log('Updated user:', updatedProps);
}

updateUser({ name: 'Jane Doe', age: 30 });
