title: Each blocks

If you need to loop over lists of data, use an `each` block:
|
|
|
|
```svelte
|
|
<ul>
|
|
{#each cats as cat}
|
|
<li>
|
|
<a target="_blank" href="https://www.youtube.com/watch?v={cat.id}" rel="noreferrer">
|
|
{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]`.
|
|
|
|
You can get the current _index_ as a second argument, like so:
|
|
|
|
```svelte
|
|
{#each cats as cat, i}
|
|
<li>
|
|
<a target="_blank" href="https://www.youtube.com/watch?v={cat.id}" rel="noreferrer">
|
|
{i + 1}: {cat.name}
|
|
</a>
|
|
</li>
|
|
{/each}
|
|
```
|
|
|
|
If you prefer, you can use destructuring — `each cats as { id, name }` — and replace `cat.id` and `cat.name` with `id` and `name`.
