In blow, I pass the test. Bu I could not understand this part of Object.keys(). I read the instructions. I need return an array. But why is this correct ?

```auto
let users = {
  Alan: {
    age: 27,
    online: false
  },
  Jeff: {
    age: 32,
    online: true
  },
  Sarah: {
    age: 48,
    online: false
  },
  Ryan: {
    age: 19,
    online: true
  }
};

function getArrayOfUsers(obj) {
  // change code below this line
return Object.keys(users);
  // change code above this line
}

console.log(getArrayOfUsers(users));

```
