What js is used when creating an online store in the modern world?

Question

JavaScript

Hello,
I'm completely confused, I want to make a small store "for myself". I came across the fact that I can not choose the right js-approach, I will try to explain.
Writing everything in jquery is already a sign that you are a dinosaur.
Backbone - dead or dying
Angular 1.5 - stupid to use, everyone is waiting for Angular
2.0 beta
React - your store will not be indexed, you will have to make two versions.
I tend to use the old fashioned Backbone, because For me, this is the easiest option. But what do modern stores use, of course, provided that qualified developers do it and try to do it as well as possible?

Answer 1

React - will be indexed, it can be rendered on the server. Angular 2 is possible, it is already rc.5, according to my feelings, the final will be in two versions, it can also be rendered on the server
In general, it looks like you choose a ladle without knowing how to cook soup

Answer 2

Install openCart, jQuery is used in places, and don't worry
