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

Hey Marcin,

It's looking for you to use the "this" keyword to access the object.

Here's a good write up I found through a previous post:

this is used inside a function (let’s say function A) and it contains the value of the object that invokes function A. We need this to access methods and properties of the object that invokes function A, especially since we don’t always know the name of the invoking object, and sometimes there is no name to use to refer to the invoking object. Indeed, this is really just a shortcut reference for the “antecedent object”—the invoking object.

Curious about the downvote here. If there's an issue with my attempt to assist I would be interested to hear your feedback.

sorry didn't do it on purpose. I was checking it on my phone and had to missclick it. Thanks a lot I solved it :)

do you mean sth like

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

You can just change the sixth line of your original post to

if (this.isTurn){};
