Question: In groovy the `.&` operator converts a method in a closure. In Java using the reflection Method object, one can get the method name, parameters names and types. Is there a way to get all the method reflection information from the closure? I'm only able to get the parameter types so far (via `closure.parameterTypes`)

Answer: 
Just use the React.js Perf API, [here](https://facebook.github.io/react/docs/perf.html).
Don't forget to use development's React bundle and not the production one.
I don't why it's not showing for you but have you tried using componentDidMount() rather than inside of your render? 

Also, React's performance tools do a great job detecting wasted renders:
