Return value and the according text with javascript

I have this piece of code (it is part of a large javascript code) and I want it to return 'article' or 'articles' as well as the quantity.

If the var quantity = 1, it should return '1 article'. If the var quantity = 0 or any other number, it should return 'x articles'

    quantity: function () {
                    var quantity = 0;
                    simpleCart.each(function (item) {
                        quantity += item.quantity();
                    });

                    return quantity;
                },

Can someone please show me how to do this? Thanks in advance.

return quantity==undefined?'':quantity==1?'1 Article':quantity+' Articles';

A simply ternary would work:

quantity: function () {
    var quantity = 0;
    simpleCart.each(function (item) {
        quantity += item.quantity();
    });

    return quantity + (quantity == 1 ? ' Article' : ' Articles');
};

As you've said you're new to JavaScript, the ?: operator is basically a compact form of if in the form expression ? when-true : when-false.

quantity: function () {
    var quantity = 0;
    simpleCart.each(function (item) {
        quantity += item.quantity();
    });

    return (quantity == 1) ? '1 article' : $quantity + ' articles';
}
