disposing of a `createRoot` nested inside a `createEffect`?

I am creating a nested effect, like:

createEffect(() => {
  // create nested effect
      createRoot(() => {
        createEffect(() => {
// ...

createEffect(() => {
  // create nested effect
      createRoot(() => {
        createEffect(() => {
// ...

Will the root be automatically disposed when the scope of the first createEffect gets disposed? How can I inspect that?

1. roots won't ever be disposed manually - you control the disposal 2. not passing a parameter for the dispose function will actually create a "top-level" (unowned) root that doesn't have access to the context - creates it's own tree 3. you can use solid-devtools to see roots, where they are and when they are disposed

what's the dispose function?

createRoot(dispose => { dispose() })

Oh thanks a lot! It's really obscure. How come it's not returned as a value on createroot? The scope seems kinda weird

You can return anything from root, including the dispose function

oh. I... Did not know that.
