Not sure why this is not accepted

I'm supposed to set the value of isTurn to false, and for some reason (maybe this is an archaic method ) this isn't working.

changing_properties.js 
const player1 = {
    name: 'Ashley',
    color: 'purple',
    isTurn: true,
    play: function(){
        if (this.isTurn) {
            console.log(`${this.name} is now playing!`);
            this.isTurn=false;
         }
    }
}

const player2 = {
    name: 'Guil',
    color: 'red',
    isTurn: false,
    play: function(){
        if (this['isTurn']) {
            console.log(`${this['name']} is now playing!`);
        }
    }
}

The instructions are for doing it after the existing code. So you did set the value correctly using dot notation, just in the incorrect spot.

After all the existing code, change the value for player1

/** existing code**/

yourAnswerHere (player1.isTurn = false)

Notice, the need to change from this to player1 since we are no longer in the scope of the object itself

I tried that after I tried "this" for that very reason. After being denied, I then went back to "this" because I didn't understand why that would be separated from the function.
