My understanding is that the client side JS is a result of backend compilation. How does this work if the backend is dynamically generating those JS files? `getPosts()` can return a different JSX based on what `getPosts()` returns. No?

(At least in React) the JSX gets transpiled to function calls, which are then run at render time with a particular set of data. That first transpilation step will always come out the same and can be cached.
