I am using pdf.js library in a js page and it works fine. However I want to know if it is possible to change the path of the library using other method instead of:

var url = 'something/helloworld.pdf';
var pdfjsLib = window['pdfjs-dist/build/pdf']; <- How can I change this to a relative/absolute path?

// Asynchronous download of PDF
var loadingTask = pdfjsLib.getDocument(url);
loadingTask.promise.then(function(pdf) {
  console.log('PDF loaded');
