Hey, why is this expected?
It seems kind of strange to me that it doesn't work straight away:
let { count, increment } = createCounter();
from svelte.
This is expected, you need derived to make the variables reactive:
let { count, increment } = $derived(createCounter());
from svelte.
count
is a primitive value, without any further added logic, the destructuring will cause it to be read (and thus copied) once and never change.
There is no good way for Svelte to know that it needs to add that extra logic here to keep updating the value.
Treating everything as potentially changing could cause other issues and adds overhead in computational cost and bundle sizes.
