Each blocks

If you need to loop over lists of data, use an each block:

<ul>
	{#each cats as cat}
		<li><a target="_blank" href="https://www.youtube.com/watch?v={cat.id}">{cat.name}</a></li>
	{/each}
</ul>

The expression (cats, in this case) can be any array or array-like object (i.e. it has a length property). You can loop over generic iterables with each [...iterable].

If you prefer, you can use destructuring — each cats as { id, name } — and replace cat.id and cat.name with id and name.

In some cases, you will need to use keyed each blocks. We'll learn about those later.
