How to run an external script in SAP Analytics Cloud application / user story?

Question

I would like to run an externally hosted script in my SAC Analytic Application.

I know this is how it can be done in regular JavaScript:

function loadExternalScript() {
   var script = document.createElement('script');
   script.src = '/path/to/my/script.js';
   var head = document.getElementsByTagName("head")[0];
   head.appendChild(script);
}

Is there a way of doing the same thing in SAP's JavaScript-based language?
