Help...

This is where I'm at:

function arrayCounter (array) { if (typeof array === 'undefined'){ return 0; } return array.length(); };

I don't really know how to go at this one.

Hi Trevor,

you are forgetting your 'else' in your condition. Also length is a property, not a function. by typing length() you are calling a function. You need to lose the parentheses.

This is what it should look like:

function arrayCounter (array) { 
    if (typeof array === 'undefined') { 
        return 0; 
    } else {
        return array.length;
    }
};

Hope this helps you out. Cheers!
