What Svelte used to be pre version 5 I think? They now also have a runtime with hooks, etc
Svelte did always have a runtime, they're still doing this from what I understand the major part of Svelte 5 was moving to signals.
I remember them advertising Svelte as the framework that disappears in build time.
The core selling point with Svelte (as I understood it anyway) was that it was a framework that compiles itself away, leaving you with a very small final JS bundle. The changes in 5 make some things more explicit/verbose but I think that core intent is still the same.
I was about to comment this. The selling for svelte has always been that the compiler will output just the needed instructions for the expressed transformation. No virtual DOM.
