1) ```js const { password, ...userWithoutPassword } = user; return userWithoutPassword ``` 2) ```js delete user.password; return user ```

const { password, ...userWithoutPassword } = user;
return userWithoutPassword

const { password, ...userWithoutPassword } = user;
return userWithoutPassword

delete user.password;
return user

delete user.password;
return user

The first one copies the user object, creating new memory. The second one modifies the object, without any new allocations. From a performance standpoint, the second one is better. But the first one is more intuitive
