We should have git tags and GitHub releases to track versions

Currently is empty: https://github.com/NeilFraser/JS-Interpreter/releases

I don't know which git commit does the versions here: https://www.npmjs.com/package/js-interpreter-npm, like 1.0.4 point to?

At the moment, it points to Master. My plan was to release with NPM every 3 months, checking with Neil if he felt that a new NPM version was warranted for.
I would be also totally happy to follow git tags and match Github releases if that's the path Neil takes.
