I'm really confused here. I Keep getting the following error "Expected the 'printFullName' function.

Hi Guys,

I'm really confused here. I Keep getting the following error "Expected the 'printFullName' function. To fix this I've tried the following.

  • leaving the printFullName function in the top
  • adding printFullName after the fullName key like this. "fullName: function printFullName(){..."
  • can also calling the function from the object.

Any help on this would be amazing, I really dont know what I've done wrong!

object.js 
function printFullName() {
  var firstName = "Andrew";
  var lastName = "Chalkley";
  console.log(firstName + " " + lastName);
}

var contact = {
  firstName:"Andrew",
  lastName:"Chalkley",
  fullName: function() {
  console.log(contact.firstName + " " + contact.lastName);}
}

function printFullName() {
  var firstName = "Andrew";
  var lastName = "Chalkley";
  console.log(firstName + " " + lastName);
}

var contact = {
  fullName: function(){
     var firstName = "Andrew";
     var lastName = "Chalkley";
     console.log(firstName + " " + lastName);
  }
};

No problem :) It has something to do with the way objects behave in JavaScript. If you wanted to do it with properties, in this case you'd use the 'this' keyword instead of the object name when referencing the properties. So 'contact.firstName' would become 'this.firstName.'
