Every time that a feature of ECMAscript specification is implemented (see link below) in V8 Javascript Engine from Google Chrome browser we are never know when will be available on NodeJS Server. I always wanted a simple way to find out that information typing into Terminal on Bash command line (CLI).

ECMAScript Compatibility Table:

Well, now I would like share it with you!

  • May be helpful for some people reaching this page via web search: v8.dev/docs/version-numbers which links to omahaproxy.appspot.com which has chrome --> v8 versions (but if you're not stuck in a cli, then chrome://version is best as mentioned in the accepted answer) – user606179 May 17 '19 at 15:33

For check the current version installed of Google Chrome browser, NodeJS Server or V8 Javascript Engine from NodeJS, type into Terminal on Bash CLI:

$ 
$ google-chrome --product-version
  63.0.3239.84
$ 
$ node --version
  v8.9.3
$ 
$ node -p process.versions.v8
  6.1.534.48
$ 

No needs Grep or AWK or Sed to trimming the text resultant!

For check the version of V8 Javascript Engine from Chrome browser, type the URL chrome://version on Address bar.
