Checking if an Object has its own property issue

[carral.ervin]

Tell us what’s happening:
Describe your issue in detail here.
So basically I was asked to make a function so when Alan, Jeff, Sarah, or Ryan is passed through isEveryoneHere() it should return true. I just wanted an explanation on why this didnt count as a pass. the question is from javascript algorithms and data structures basic data structures check if an object has a property

  **Your code so far**

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

function isEveryoneHere(userObj) {
  if (users.hasOwnProperty(userObj)) {
    return true
  }
  return false
}

console.log(isEveryoneHere('Ryan'));

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

function isEveryoneHere(userObj) {
if (users.hasOwnProperty(userObj)) {
  return true
}
return false
}

console.log(isEveryoneHere('Ryan'));

function isEveryoneHere(userObj) {

first, the function is being passed in the object, userObj in this case is equal to users

you need to check that all four required properties, Alan , Jeff , Sarah and Ryan, are present in the object

also you never user users in your code, you instead need to always use userObj to access the object
