I'm a newcomer to React, and I was wondering something. If a site has been built using React, will I always be able to see that in the source code from the developer tools? I installed the ReactJS Super-Powered extension for Chrome, but I don't know how reliable it is.
What should I be looking for if I want to spot React in the code?

React is one of Facebook's first open source projects that is both under very active development and is also being used to ship code to everybody on facebook.com.

React devtools has many features.

And react uses specific keys to keep track of the dom and keep it quick which could possibly be recognized in the dom.
