What are drawbacks of using React JS?

[pharmasecure]

Disadvantages of using React:

React.js is only a view layer.
Integrating React.js into a traditional MVC framework such as rails would require some configuration (i.e., substituting erb with React.js).
There is a learning curve for beginners who are new to web development.

the library itself is pretty large.
the learning curve can be steep.
