Quoting from the article:

"In 2009, CommonJS was exactly what JavaScript needed. The group took a tough problem and forced through a solution that continues to be used millions of times a day.

But with ESM as the standard and the focus shifting towards cloud primitives — the edge, browsers, and serverless compute — and CommonJS simply doesn’t cut it. ESM is a better solution for developers, as they can write browser-compliant code — and for users who get a better end experience."
