However, with the release Node.js 14 support for ECMAScript modules (also known as “ESM”) landed. Node.js itself did not initially offer support for ECMAScript modules in large part because of the problems associated with being able to support CommonJS as well as ECMAScript modules.There was already an established module system used in Node.js called CommonJS.Whilst writing code using ECMAScript module semantics came quickly for front end, for the back end (which is generally Node.js) that has not the case.

These days they are called ECMAScript modules. When ES6 shipped back in 2015, with it came the concept of modules for JavaScript.
