JavaScript Object-Oriented JavaScript (2015) Introduction to Methods Adding a Method to an Object

Create a method on the contact object called fullName, use the programming from the printFullName function.

What's wrong...?

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

var contact = {
  var fullName={
printFullName();
};
}

I would highly recommend going back and watching the previous video again to see how Andrew defined a roll method on his dice object.

Looking at your current code, contact is an object, so properties and methods on objects are formatted like this:

var anObject = {
  propertyName1: "Hello",
  propertyName2: "World",
  methodName: function() {
     console.log(this.propertyName1 + " " + this.propertyName2);
  }
}

As shown above, object properties aren't defined the same way as variables are. While you can't define variables inside an object the way you've done so in your code, you can, however, do so in a method like this:

var anotherObject = {
  methodName: function() {
    var string1 = "Hello";
    var string2 = "World";
    console.log(string1 + " " + string2);
  }
}

Hopefully you can use this as a reference to complete the challenge. If you continue to get stuck or if anything I've mentioned above isn't clear, please let me know.

Mmh I think I get what you're telling me but still stuck with "parse error" on this:

var contact = {

fullName: printFullName(){

  var firstName = "Andrew";

  var lastName = "Chalkley";

  console.log(firstName + " " + lastName);

}}
