<svelte:component>

A component can change its category altogether with <svelte:component>. Instead of a sequence of if blocks...

{#if selected.color === 'red'}
	<RedThing />
{:else if selected.color === 'green'}
	<GreenThing />
{:else if selected.color === 'blue'}
	<BlueThing />
{/if}

...we can have a single dynamic component:

<svelte:component this={selected.component} />

The this value can be any component constructor, or a falsy value — if it's falsy, no component is rendered.
