Echo JS 0.11.0

I think this module's role is different with classList.
As you said, classList is a API of DOM.
But this module just generates a string.
So... I think this module is useful for framework or library user(React, Angular, Vue)
In VanillaJS, absolutely classList is good :)

And no worries, I'm not care about the downvote.
All of positive or negative opinions always welcome!
