JavaScript Object-Oriented JavaScript (2015) Introduction to Methods Understanding this

I'm constructing an object with properties and a console.log() call. Why isn't it recognizing my property values?

This is my object:

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

It's telling me that it's contact.firstName and contact.lastName are undefined, not objects ...

I also tried this.firstName and this.lastName, still didn't work. Help :(

object.js 
var contact = {
  firstName: "Andrew",
  lastName: "Chalkley",
  fullName: console.log(this.firstName + " " + this.lastName)
}

console.log doesn't belong inside of your object. I'm taking a small guess here as I haven't tested it but "this" is typically used to access properties on within a function. I'm not sure if you can directly access the values your setting while creating the object but just in case, try fullName: contact.firstName + ' ' + contact.lastName; See if that helps.

  fullName: function() {
    console.log(this.firstName + " " + this.lastName)
  }

Is what you are looking for, you have removed the function for some reason :)

Thank you! I thought I did try that -- was probably getting frustrated and stopped, haha. Thanks a bunch!
