Here's a few hints:

  • when referring to instance attributes, use "this" instead of the variable name
  • a single = is an assignment operator, that's not what you need in an "if" expression
  • when testing a boolean value, you don't need to compare it to "true" — just name the value

i tried this

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

but i got unexpected identifier

It looks like you have unbalanced braces here. And you still need to use "this" instead of the variable name.

To check if condition is true you need == operator not = and i believe the challenge wants you to use the this keyword to target the object property, fix these 2 steps and you will do it

I tried this, but still no luck... I'm having the same problem as Haardik.

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

    };
}

You have a colon in the wrong spot. Try resetting the challenge and adding everything from there. You are on the right track. Remember you don't need to set a boolean value to true in an if statement. You just need to name the value by itself for it to be true, if you wanted to set it to false it would look like if(!this.isTurn){ }

i have fixed the code but am still getting

unexpected token function

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

};

}

Haardik, I'm still seeing unbalanced braces (3 open, 2 close). And the colon after "play" seems to be missing now (I do not understand the colon comment Kostatinos made).
