Why did we create a variable called type in the video? I don't understand the purpose of that in the code or is it supposed to be just an example? Example of what exactly?

Thanks for any help ! :)

Hi! :-)

The reason he created the variable named type, is just to illustrate that the object "Contact" can have multiple properties - first name, last name, and "type" - which means what type of relation it is. It could be a friend, your mom or your dogwalker. It's an example of how complex the objects can be. I hope that makes sense :-)
