How do I set Space object’s token property to the Token object?

In the challenge, It wants me to set the Space object’s token property to the Token object passed to the method. But I think I might be overthinking it.

here is my code.

    mark(token) {
        this.token = token;
    }

Yes, that's correct.

this.token is the Space object's token property, which you see in the Space constructor method. Then you're setting it to token, which is the argument that holds the Token object passed to the method.

For clarity, this could also be written with token being renamed to anything else. For example:

mark(argument) {
    this.token = argument;
}

argument can be named anything and becomes whatever is passed to the mark method when we call it (though we haven't done that yet). In this case, our argument is going to be a Token object, so we name it token.
