How to check if the Entry field type relation is empty in antlers?

[JeremyWorkWork]

I have a collection called Products
I have a collection called Categories

Products has a Entry field type relation

  handle: categories
  field:
    type: entries
    taxonomies:
      - categories
    display: categories
    mode: default
    create: true
    collections:
      - categories
    icon: entries
    listable: hidden
    instructions_position: above
    visibility: visible
    hide_display: false

In my antlers template for the product collection:

{{ categories }}
    {{ title }}
{{ /categories }}

If the Product collection has related categories then the title is of the category title, if there are no related categories then the title is of the product.

Categories always evaluates to true even if there are no relations. Hence the above outputs the product title if there are no related categories

How can i loop the related categories alway as an array or at least check if there are no related categories?

Do i need to use something like this to check the raw value first?
{{ if categories | raw }}

is_empty modifier doesn't seem to help.

dumping out $categories when there are no relations shows the Statamic\Fields\Value instance with a raw value of null.

dumping out $categories when there are relations shows the Statamic\Fields\Value instance with a raw value with the array of related entry ids.

{{ if (categories | count) > 0 }} should work for this

Thanks, works. I missed that.

Also possible to simplify to {{ if products | count }}
