Notable Changes

Automatically detect and run ESM syntax

The new flag --experimental-detect-module can be used to automatically run
ES modules when their syntax can be detected. For “ambiguous” files, which are
.js or extensionless files with no package.json with a type field, Node.js
will parse the file to detect ES module syntax; if found, it will run the file
as an ES module, otherwise it will run the file as a CommonJS module.
The same applies to string input via --eval or STDIN.

We hope to make detection enabled by default in a future version of Node.js.
Detection increases startup time, so we encourage everyone — especially package
authors — to add a type field to package.json, even for the default
"type": "commonjs". The presence of a type field, or explicit extensions
such as .mjs or .cjs, will opt out of detection.
