JavaScript Object-Oriented JavaScript Object Basics Filling Out the Play Method

I don't know how to use Java script dot notation with an if statement. How do I solve this problem?

const player1 = { name: 'Ashley', color: 'purple', isTurn: true, play: function(){ // write code here. (I know the If statement goes here but I don't know how to combine it with java script notation. } }

object.js 
const player1 = {
    name: 'Ashley',
    color: 'purple',
    isTurn: true,
    play: function(){
        // write code here.
    }
}

There's an example of the dot notation being used in the Teachers's Notes section at the bottom of the previous video page. The main difference is that example adds two of them in a console.log statement, but here you only need one in an if statement.

I just had a look at the example in the teacher's notes. I'm still confused. Could you simply write out the code?

Give it your best "good faith" try, and if you have trouble, show the code you wrote here and I'll help you with it.

Actually I tried several times before I asked for help. I got nothing but error messages. Here's one approach I tried.

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

You're close! But the code inside an object doesn't refer to itself by name, but with the special keyword "this".

Fix that, and you'll have it.

I tried running the below code and it doesn't work. I understand that you're trying to be helpful but not being able to solve this problem is becoming very frustrating for me. Please provide me with the correct answer and, if you like, an explanation of what I was doing wrong to help me fully understand this exercise.

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

You were closer last time, all you need to do to the previous code is replace "player1" with "this" in the "if" expression.
