This might be possible in simple cases, but there are two reasons I think.

1. React has an ethos of being “just JavaScript” (despite the JSX syntax which is purely sugar around calls to React.createElement). This means the core team doesn’t seem to be interested in adding an extra compiler step. 2. Related to the above, because React is just JS, you can do all the normal and horrible things with it you can do in JS. Wanna pass React elements around in context or even using global variables? That’s allowed. A compiler could probably handle a lot of simple cases but there’s a whole lot of things it wouldn’t be able to deal with.
