Order of the arguments in the constructor parameter

class Token {
    constructor (index, owner) {
        this.owner = owner;
        this.id = `token-${index}-${owner.id}`;
        this.dropped = false;
    }

I could not understand why the 'index' argument should be put as the first argument. When I put 'owner' as the first argument as below, the token will be missing.

class Token {
    constructor (owner, index) {
        this.owner = owner;
        this.id = `token-${index}-${owner.id}`;
        this.dropped = false;
    }

When you initialized the class passing in those arguments, where they in the order expected? Or is treehouse calling the class in a particular way that you don't have visibility of during testing?
