More detailed, ES modules was experimentally supported since Node.js 
v8.5, and since v14 it is considered stable.

A good thorough explanation of using a mixture of old-style CommonJS and 
new-style ES modules:

A nice relatively short post about migrating a project from CJS to ESM 
(from a fan of mine):

ES modules is a JavaScript language feature introduced with ES6 a.k.a. 
ES2015. NodeJS was invented before ES6 and have used another less 
efficient modularizing method called CommonJS (or CJS).
