Enforce ES5 or ES6 class for React Components (react/prefer-es6-class)

React offers you two ways to create traditional components: using the ES5 create-react-class module or the new ES6 class system. This rule allows you to enforce one way or another.

Rule Options

...
"react/prefer-es6-class": [<enabled>, <mode>]
