why would you assume reactive frameworks to be slow?

not assuming to be slow, I’m just assuming it’s not suitable for something like a gaming engine to be written in it. There is always going to be some amount of overhead to finding the changes in the shadow dom that’s generated.

there is no shadow/virtual dom. the compiler plugin rewrites composables to allow changes to propagate granularly. composables are not pure functions to an intermediate tree that then needs diffed.

@jw Oh - I see. Thanks for correcting my poor assumption. What do you mean

propagate granularly

?

if you only change a single property of a composable then that is all that's changed in the next rendering
