Proper ESM usage?

Could we get this for proper ESM usage so not defined directly in window as well a method to handle console.log out with our own functions?

Current usage is:

import basic from "https://esm.sh/gh/google/wwwbasic/wwwbasic.js" // from NPM
// var basic = require('./wwwbasic.js'); // from within the cloned repository directory
 window.Basic(
`
PRINT "Hello World!"
FOR i = 1 to 10
  PRINT "Counting "; i
NEXT i
`);
