Just like in JavaScript, an if block can have an else block:

App
{#if count > 10}
	<p>{count} is greater than 10</p>
{:else}
	<p>{count} is between 0 and 10</p>
{/if}

{#...} opens a block. {/...} closes a block. {:...} continues a block. Congratulations — you’ve already learned almost all the syntax Svelte adds to HTML.

<script>
let count = $state(0);

function increment() {
count += 1;
}
</script>

<button onclick={increment}>
Clicked {count}
{count === 1 ? 'time' : 'times'}
</button>

{#if count > 10}
<p>{count} is greater than 10</p>
{/if}
