My sense of JS frame

For some JS framework in my opinion, are the front-end performance dynamic, that is, with dynamic JS to load HTML into the page, such as ANGULARJS's MVVM development mode (has been contacted), Reactjs View layer Component (learning), there are some have only heard, have not seen the framework has not heard.

Now I feel that this development mode, which is dynamically written to the Web page through JavaScript, is very unfriendly to SEO support, and it is really a great innovation from the perspective of development and maintenance.

Angularjs is through the development of the project to learn, feel good, because SEO unfriendly, but also developed 80%, access speed is also very fast (application is a single page mode, just contact can only refer to some of the Great God's demo), and finally gave up the restore back to the previous version. Through that period of development to angular also have some understanding, that is I turn the front-end contact after the first front-end framework;

There was no sense of the front end is so advanced, but in the contact with the Angularjs, feel the front end of the road is very long, and then began the system of learning the front-end framework. In the project development idle time to learn the REACTJS framework, understanding that the framework is the MVC pattern of the View layer extension, the simplest demo of their own to do some testing, but the framework is not yet to reach the extent of understanding. So intend to learn the system under. And I give up angularjs no longer in-depth study is because angularJS2.0 has been released, and it is completely different from the previous angular, I think that the cost of learning 1.0 is too high, so temporarily put down, until 2.0 mature reference materials after the pick up and re-study.

AngularJS and Reactjs are the current relatively hot frame, want to learn the front-end must understand them!!!
