How to access the class name of a React object in this.props.children

Warning: this will not work in production if using minification

In ES6 every function has its name stored in property function.name so you can get Class name with

import React from 'react'

...

getNameOfChildrenClass() {
    const singleChild = React.children.only(this.props.children),
          childClass = child.type

    return childClass.name        
}

I'm using React.children utility
