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 }" 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:
{# 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.
