At least with solid, you can't do `const a = <jsx>` without caveats. Instead you have to store it as `const a = () => <jsx>` (which isn't quite the same, having problems managing state/renders). In React I was optimizing things by storing vdom in state/memo & then interpolating that exact vdom. Or sharing vdom in multiple places. Without vdom you can't throw jsx results around so haphazardly

In solid there's also managing batching updates to reduce rerenders since it eagerly updates dom. It feels like one needs to be more meticulous
