что-то я там не увидел ответа на мой вопрос)
ты только первый ответ прочитал?)
Here are some requirements driven reasons I've mixed the two:
1.) We wanted to render some advanced components server side with Node.js and ReactJS is excellent at this.
2.) Some advanced front-end components were wonky with AngularJS. Especially components that are repeated a lot of time on a page. Think a product grid on an e-commerce site. Replacing these components with ReactJS was fairly easy and yielded great speed and consistency improvements.
3.) ngOptions is great but ngRepeat creates a lot of scopes and is 100% destructive when you are rendering lists. Replacing custom grid and list type components with ReactJS reduces TONS of watchers, scopes, and DOM manipulations.
