[Falcor] Building Paths Programmatically

        model.setValue('genreList[0].titles[0].rating', 5)

                .then(function (value) {

                    model.get('genreList[0..1].titles[0]["name","rating"]')

                            .then(function (json) {

                                console.log(JSON.stringify(json, null, 3));

                            })

                });

In the code, we use Javascript path (dot): genreList[0..1].titles[0]["name", "rating"];

We can also use array syntax:

["genreList", {from: 0, to: 1}, "titles", 0, ["name", "rating"]]

They achieve the same result, but using array syntax is more flexable:

var index =0;

["genreList", {from: index, to:index+ 1}, "titles", index, ["name", "rating"]]

Because you can ember the variable.
