I do not understand how to add an empty method to an object literal called play() to this exercise.

Am I suppose to add an new object literal?

object.js 
const player1 = {
name: 'Rhonda',
color: 'pink',
isTurn: true,
}

Hi Rhonda,

This challenge is asking you to modify the existing object literal, buy adding an empty method.

An empty function outside of an object might look like this:

function my_function()
{
        /* nothing going on here */
}

or this

function my_function() {}

or even this

let my_function = () => {}

In an object methods are stored in a similar way to other properties.

const some_object = {
        prop_one: "value";
        my_method: function() {}
}

If I wanted that method to do something I'd need to fill out the curley braces. Just like with all of the other empty functions above.

Best of luck!

Eric

Ok, so all you need to do is remember how you define functions in JavaScript like so:

function name() {

}

However, we can also create a function through variables like this:

let name = function() {
}

Well in a method the attribute is like a variable but we remove the let/var/const identifier, and replace the = with a :

so we are left with this:

name: function() {
}

Hopefully this should be enough information for you to solve the challenge!

Ha, good answer yourself! I always find it's helpful to have the same concept explained from different perspectives, so hopefully Rhonda gets something from having both of these explanations!
