Maybe this question is trivial, but researching in several import/export docs did not give me an answer. I am trying to understand a code snippet that starts with the following imports on a CodePen example:

const Point = ol.geom.Point;
const RMap = rlayers.RMap;

I would rather expect module imports like this:

import { Point } from "ol/geom";
import { RMap } from "rlayers";

I thought it might be related to some hidden CodePen functionality, but also could not find an explanation. The CodePen is here https://mmomtchev.github.io/rlayers/#/add_delete when you click on the CodePen button. You can see in the JS settings that the CDN https://cdn.jsdelivr.net/npm/rlayers@1.4.1 was added. But I don't see how this would allow
the syntax given above. It did also not work, when I tried on a new CodePen.
