If/else block for post categories

I want to display a joined list of post categories if set, or default alternate text if not (pseudo code)

if post categories
categories.join(', ')
else
default text
end

How would that be accomplished in a micro.blog template?

Thanks!

I’ve figured this out with help from here: Error calling delimit: can't iterate over <nil> - #2 by regis - support - HUGO

{{ if .Params.categories }}
  {{ delimit .Params.categories ", " }}
{{ else }}
  Post
{{ end }}

If you skip the if block and just do delimit, then you may run into a nil error resulting from trying to iterate over a nil value.
