It's automatic:

I tried to make the example as minimal as possible, so I don't show off a lot of the features (i.e. state, event handling), but I did use JSX, an optional syntax extension for function calls.

Thank you, this seems to do it for the innerText. Would it be too hard to apply it to the class attribute too? (I've tried to just copy the {} binding, but it doesn't work)

Thank you both! I now have a much better understanding on how React works. I need to update the related performance benchmarks, it would be interesting to see how they compare side-by-side on our use cases.

Don't forget [PureRenderMixin][1], it can give a big perf boost when used in right places.
