Here are two methods that can be use to find the version of the V8 engine that a particular version of node is using.
if you can run nodejs
To display the V8 version, you can simple execute the following command:
$ node -e "console.log(process.versions['node'],process.versions['v8'])"
if you cannot run nodejs
- read the nodejs Release note at http://nodejs.org/changelog.html
- scan the file to detect when the V8 engine was upgrade and note the corresponding node version.
