Will we replace backbone js today?

Question

backbone.js

I often see that vacancies require knowledge of backbone.js, which is missing.

Apparently at the time of its popularity, everyone built "applications" on it. And rewriting such a large application is already hard.

Questions:
1. Is it worth studying today (regardless of the vacancy)?
2. Will it be replaced today?
3. Is it worth building an application from scratch based on it?
4. Cool technology?

3. From scratch, I would not build, but if you don’t know anything else, then, as they say, what to do? =)
