Why not use ES6?

[GuoXiaoyang]

Sorry to disturb you. I think your resume template is helpful. However I just wondered why you do not use es6 which I think will make the code more clear...

@GuoXiaoyang I am using ES6 aspects. Specifically, I am using const for variable declarations everywhere.
But I guess you're referring to using ES6 classes for React class creation?

I have been meaning to do this, just have not had the time to make the switch.
One thing I do not like about using ES6 classes to extend React.Component is that, we lose the auto-binding capability and we need to bind the context separately. I was initially hesitant to make this switch before and that is why I introduced create-react-class as a dependency, but now having seen a number of examples, I will switch to using arrow functions in method definitions.
