I think without using something like Flow or TypeScript, it’s impossible to
determine type of the value for an AST node. Sorry, I’m not aware of anything
that would allow you to do it, and I’m not really sure it’s possible to do in
the first place.
Thanks,

Subject: [ESLint] Good AST node assertion library?
Hi all,
I'm currently creating an eslint plugin for MongoDB queries/updates linting and
for this work i need to guess the resulting type of a particular AST node at
execution.
By example, knowing if a particular AST node will always return a number, a
date object or a string or if it is impossible to know it for that particular
node.
I started factorizing the code here
https://github.com/nfroidure/eslint-plugin-mongodb/blob/master/src/lib/utils.js#L101
but i'm sure i'm missing some great library that could do it for me.
Despite my various search i couldn't find it, does some of you know an existing
library allowing to do that kind of things?
Thanks in advance.
