This demo shows that eslint-plugin-fp doesn't seem to work when run in Jest via ESLint Node.js API, ESLint reports an error for every fp/* rule, for example:

Definition for rule 'fp/no-let' was not found  fp/no-let

as if I didn't add fp to plugins in my ESLint configuration.

• this only happens with eslint-plugin-fp, I threw eslint-plugin-import in there, too, and it works
• this only happens in combination with Jest, try running yarn script which also runs ESLint via Node.js API, and it works

That's as far as I got. 😄
