Is root's +layout.svelte function that onMount maybe returns ever called?

I'm wondering if it makes sense to return something from there since I don't think it ever gets called anyway because I don't see when it can be executed if for example the browser window is closed.

What do you think?

Hi, @frederikhors.

Thanks for taking the time to ask a question.

I'm unsure what you mean by this part:

if it makes sense to return something from there

Can you share some insights into what you are trying to achieve?

I'm referring to this case:

• file: /src/routes/+layout.svelte

<script lang="ts">
	import { onMount } from 'svelte';

	onMount(() => callMe());
</script>

Hello!

If callMe returns a function would ever be called given that we are in the basic layout of the entire Svelte app?

And if I close the browser window or the PWA window on the device I assume that the eventual function will never be called, right?
