Which JavaScript Framework to choose for complex applications?

Question

JavaScript

I do a lot of development of various admin panels and web applications, where there are a lot of different tables, trees, windows, dialogs, graphs, etc. In general, applications in terms of interface resemble ordinary desktop windows applications for working with specialized databases or, in some ways, 1C applications. A beautiful design is not very critical here, but the presence of a large number of controls and usability is critical.
Right now I'm doing all this mostly with jQuery UI and Twitter Bootstrap with different plugins, but it's not very productive. Yes, and you can’t make very complex interfaces with this approach. You have to implement a lot yourself, third-party plugins are not always architecturally compatible.
In general, I want to choose a good platform, with a good set of standard GUI elements, with a clear and flexible architecture, and with an acceptable entry time.
I looked in the direction of Sencha, but there is a lot of criticism and the price of more than 4K dollars is a little annoying.
What can I advise?

Answer 1

Now Angular.js is very fashionable, and thousands of plugins and extensions, including Angular UI, are written for it.

Answer 2

Perhaps it will help: Is it possible to write a complex web interface like 1C under a browser and what is better to use?
