NodeJS Build Versioning

node.js version	release of nodejs you are using
npm version	npm is installed with nodejs, but versioned separately
V8 version	the chromium javascript engine version built into this nodejs version
NODE_MODULE_VERSION	C extensions built in node are built using a specific target node module version. I think this might be a C runtime. This is generally stable for a wide range of nodejs versions.

See this version-info chart.

Managing Node Versions

You can use nvm to manage node versions.

nvm run 16.0.3 node foo.js  # run nodejs -v 16.0.3
