Elixir/Phoenix is awesome, no complaints overall. A few small things:

- Passing data from LiveComponent's/JS is a bit of a pain (need to use update())

- phx-hook doesn't always pay well with re-rendering state changes

- Directly calling JS functions (e.g, getting Apple Pay to work) isn't clean

- Can't use attr when using LiveComponents (need to wrap them in a functional component)

- Unique ID requirement for LiveComponent is a pain (so is wrapping them in a div)

- No great APIs for updating session data when using sockets

- Can't pass params to LiveView in live_render, have to use session
