How do I view the source code version? (List what you know)

  git, question

There are often such problems. I downloaded a copy of the source code before and when I read it again after a while, I don’t know the version of the code.
If it is js/npm code, I know to look at the package.json file, but the others don’t know which to look at.

such asnode.js v8This code written in c++?

Can you see it in git’s log?

Other java,python,swift, etc. can also be said

As for the comments in the header file that can be read by C++, some will have a macro definition to mark the version of the current code. If there is a CHANGELOG file, it can also be used.
