I figured this would be the case. This fact will contribute to lots of interesting discussions in the future regarding whether or not we should move away from JS and if so, how. Obviously having something like React is still hugely beneficial for reducing the logical complexity of creating UI, but you'd need to reconsider how you'd write your components without JSX or perhaps some language agnostic version of JSX would need to be created.. Or maybe we just implement E4X type syntax in other languages.
