I guess a better question would of been what is React+Redux+other libraries composed to make a framework missing in comparison to Angular. I have noticed I can make many things in Angular like react but they seem to be against the idea of how angular works and overall creates more bloat than actual functional code.
I really like react and haven't really gotten into working with modules with it yet but react is still younger than angularjs so it will have less libraries to work with. You can of course write your own but it is nice to just search for what you need and it already be there for you.
