Inside the play method, write an empty if statement that checks if it's the players turn. Use dot notation.

I understand the correct answer is this "this."

But why is it this "this." Instead of "player1." Where does the , this come from?

object.js 
const player1 = {
    name: 'Ashley',
    color: 'purple',
    isTurn: true,
    play: function(){
        if (player1.isTurn) {
        };
    }
}

You never want to reference an object by name from inside the object itself. Just imagine if it were copied and given a different name!

Using this is the proper way for an object to reference itself.
