What are the tools for visualizing UML diagrams for JavaScript "classes"?

Question

JavaScript

Good day everyone!
I would like to know if there is a program that generates a graphical representation (something like a UML diagram) for existing JavaScript "classes". It would be desirable that:
1. it was an independent program, and not a plug-in for something,
2. it would be possible to submit js files with the definition of "classes" between which inheritance is possible,
3. get a description of the classes at the output (with their properties and methods) and the relationship between them in graphical form.
By and large, I would like to have an analogue of RailRoady in Ruby, but for JavaScript.

Answer 1

little problem, there are no classes in js, the prototype can change at any time, so it all depends on the implementation.
