How to import javascript classes into another javascript method?

I have a JavaScript class which I created and I want to instantiate this class in another javascript method

i.e.

F2:

export default class Example {
  test() {
    console.log('hello world');
  }
}

& F1:
import Example from './file2';
var myInstance = new Example()
myInstance.test()

I have not been able to do this yet, and I'll likely need to find another way, but does anyone know? I am aware of aras.evalMethod, although I have yet to find success in terms of class instantiation with this way.
