handlerbars.js check if list is empty

Question

Is there a way in Handlebars.js templating to check if the collection or list is null or empty, before going and iterating through the list/collection?

// if lis         


        

Answer 1

If you have something that you want to display once and only if the array has data, use

{{#if items.length}}
    //Render
{{/if}}

.length will return 0 for empty arrays so we have achieved a real falsey value.
