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.
