Basic Data Structures - Check if an Object has a Property
I have to check whether the object has the mentioned properties and I have written this code which is not working for the condition when the object has all the properties.

Can you please explain what’s wrong in the code.

**My code **

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) {
  // Only change code below this line
 let user =["Alan", "Jeff", "Sarah", "Ryan"];
   if (user.forEach(e=>userObj.hasOwnProperty(e))) 
   {return true;} 
   else{return false;}
  // Only change code above this line
}

console.log(isEveryoneHere(users));

Array.prototype.forEach() - JavaScript | MDN

For each return value is “undefined” by definition.

Your thinking is good, but you’re using a wrong method on the Array object.

@tauheed2601

if (user.forEach(e=>userObj.hasOwnProperty(e)))

Go to this website and try to find the method you need.
