<svelte:self>

Svelte provides a variety of built-in elements. The first, <svelte:self>, allows a component to contain itself recursively.

It's useful for things like this folder tree view, where folders can contain other folders. In Folder.svelte we want to be able to do this...

{#if file.files}
	<Folder {...file} />
{:else}
	<File {...file} />
{/if}

...but that's impossible, because a module can't import itself. Instead, we use <svelte:self>:

{#if file.files}
	<svelte:self {...file} />
{:else}
	<File {...file} />
{/if}
