Inside the play method, write an empty if statement that checks if it's the players turn. Use dot notation.
const player1 = {
name: 'Ashley',
color: 'purple',
isTurn: true,
play: function(){
}
}

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

You will want a statement that is only true when it's player1's turn.

8,669 PointsIt's doesn't work like this, too.
const player1 = { name: 'Ashley', color: 'purple', isTurn: true, play: function(){ if(isTurn) { return player1.name; } } }

I know this post is a few months only but I figured I'd answer anyway.
Your code is almost there but it is missing the this keyword to specify where the isTurn is coming from. It should look like this:
const player1 = {
name: 'Ashley',
color: 'purple',
isTurn: true,
play: function () {
//below is where you need to include the this keyword
if(this.isTurn) {
return player1.name + " is now playing!"
}
}
}
Hope that helps!

11,835 Pointsplayer1 is an object.
To access a property in an object, you can use dot notation or bracket notation.
For example, if I wanted the name, I could type either player1.name (dot notation) or player1['name'] (bracket notation, note that it's a string within the brackets, this is because with bracket notation you can use variables and numbers as well, in fact ANY type of expression is allowed within brackets, even functions! Whereas dot notation ONLY allows strings)

Treehouse ModeratorHey thanks for the help on this it worked. But, I am kind of confused where the 'this' came from though. I don't remember anything about adding a 'this' before a dot notation.
