Modify Object with this

What am I doing wrong here, the question is: 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 = {
  fullName: function(firstName, lastName) {
    this.firstName = "Andrew";
    this.lastName = "Chalkley";
    console.log(firstName + " " + lastName);
  }
}

Hey Michael,

If you go back to this video, Andrew moves the variable declarations to a different scope (basically one up from where it is) by adding properties to the top variable declaration (in the video it's the dice variable). So, in the challenge, you need to do the same thing and move the firstName and lastName as properties to the contact variable and delete them from the function. Also, remove the properties from the function...

Don't forget to use commas after each one of the properties, including the last one.

Give it another shot. Let me know if you're still stuck. :)

Keep Coding! :dizzy:
