evalFile vs //@include

What to use when, and why?

Some background: I'm currently working on a panel in Adobe Configurator which calls scripts via links in a html widget.

Basically it looks like this:

var scriptFile = new File(app.path + '/Presets/Scripts/myscript.jsx');

$.evalFile(scriptFile, 30000);

myFunction(args);

I'm wondering when the following is preferred:

//@include myscript.jsx

myFunction(args);
