You can create recursive components in Svelte using a special component that calls the component it is defined in:

Copied to clipboard!
<script>
  export let count;
</script>

{#if count > 0}
  <span>Liftoff in {count}</span>
  <svelte:self count="{count - 1}" />
{/if}

<CountDown count="10" />
Recursion.svelte

Take note that you can only use svelte:self in an if statement to prevent infinite loops.
