How to describe and JS files with this program?

Question

Vue.js

Hello, I found such a cool library to document my components. But I can’t find in any way whether it is possible to document JS or TS files from above, at least in the form of plain text, because I would like to describe functions that are very often used inside other components and are rendered
. I don’t know how to name the program / library itself : https://vue-styleguidist.github.io/docs/Developmen...
