Modify this object so it uses two properties firstName and lastName and remove their variable declarations from the full

Modify this object so it uses two properties firstName and lastName and remove their variable declarations from the fullName method. Don't do anything to the console.log() call right now.

object.js 
var contact = {
  firstName: "Andrew",
  lastName: "Chalkey"
    Console.log(firstName +" "+lastName);
}

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

part II

var contact = {
  firstName: "Andrew",
  lastName: "Chalkey",
  fullName: function() {

hey,

If you want to log these names into the console you have to call them on their variable first. Right now you try to call two variables with the name 'firstName' and 'lastName', but there are no such variables. try to call the object variable first 'contact' followed by the dataname 'firstName'

e.g contact.firstName

hello, i'm stuck on the same challenge. i've already tried what you said up ahead, but it gets a parse error

here's the code:

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

should be, because you need to call the data in this way, not assign it this way. So it should be like:

var contact = { firstName: "Andrew", lastName: "Chalkey" Console.log(contact.firstName +" "+ contact.lastName); }

hope this helps you out
