To be Marionettejs or not to be?

Question

JavaScript

Good evening!
I am developing a plugin with an impressive client-side.
I have limited experience with Backbone.
Questions! How long will it take to learn Marionette and does it make sense? in terms of facilitating development, support, and so on. Or write on pure Backbone and gradually rewrite? Interested in the ratio of time spent in net profit, of course, the average.
Thanks

Answer 1

In short, "to be". This will allow you to avoid a bunch of rakes that you will stumble upon during development.

Answer 2

A puppet is about those auxiliary things that you yourself will write on the backbone after six months or a year of project development. Only they are already written, tested, etc. + The level of abstraction in it is chosen very correctly: it really helps, but does not interfere.
