The `process.versions` property returns an object listing the version strings of
Node.js and its dependencies.
Node.js and its dependencies. In addition, `process.versions.modules` indicates
the current ABI version, which is increased whenever a C++ API changes. Node.js
will refuse to load native modules built for an older `modules` value.

Documentation text mirrors the only available documentation for this property.... an in-source comment. @addaleax are you saying the comment is wrong?

If so, this PR should change both the comment and the docs.

@sam-github No, I didn’t say the current text is wrong. It’s just incomplete and might therefore be misleading.

If so, this PR should change both the comment and the docs.

No objections to that, but, like, this isn’t worth holding up the PR or anything imho.

Right, so text should be something like "Node.js will refuse to load modules that weren't compiled against its own
module ABI number."


```js
console.log(process.versions);
