Javascript framework?

Question

JavaScript

Recommend a good javascript framework.
Desirable:
- convenient code organization (architecture)
- execution speed
- extensibility
- availability of convenient development tools in the framework itself
For what:
To organize a large-scale javascript application that needs good structure and with the help of such a tool that will save you from inventing your own bicycles.
I considered SproutCore, but I was somewhat confused by the lack of a choice of manuals and guides for it on the Web, which may indicate a not too active community and some pitfalls when using it. In addition, its performance and interaction with node.js on the server side are in question.
Of course, this is just a subjective opinion that arose after a short monitoring of this product.
Thanks in advance.

Answer 1

We use a closure-library that includes all of the above requirements. The only problem with it is the lack of a large community like for other frameworks. Therefore, to figure it out, you have to read the code of the lib itself.

Answer 2

Read about:
AngularJS
EmberJS
BackboneJS (can be linked to ReactJS)
choose the appropriate one.
