jQuery equivalent of requirejs function : What's the equivalent of the below in jQuery?

    require(['jquery', 'SunCalc'], function ($, SunCalc) {
        var position = SunCalc.getMoonPosition(new Date(), 51.5, -0.1);
    });

I don't want to use requireJS but I want to use a specific library (SunCalc). I've installed it via npm and created a gulp task to minify the library file and include it but how could I do the above with requireJS?

Or is it required? HAH!
