I really like how with React (and a few others) you can make a quick abstraction in the same file for a repeated chunk of the render. Sometimes something warrants pulling out into a function for reusability but it doesn’t quite pass the bar to justify its own file as a component - I know there’s some template stuff coming in Svelte 5, so hopefully that scratches the itch.
Totally agree, I can definitely say I’ve found myself wishing for that more as I continue to use Svelte. I didn’t see it as necessary at first, but situations that could benefit from that have come up enough now that I’ve used it for a while
