handlerbars.js check if list is empty

Question

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.

The "each" tag can take an "else" section too. So the simplest form is:

{{#each items}}
// render item
{{else}}
// render empty
{{/each}}

Ok it's simpler than I thought:

{{#if items}}
// render items

{{#each items}}
// render item
{{/each}}

{{else}}
// render empty
{{/if}}

If you want to check if a collection (cursor) is empty or not, the previous answers won't be useful, instead you must use the count() method :

{{#if items.count}}
    <p>There is {{items.count}} item(s).</p>
{{else}}
    <p>There is nothing</p>
{{/if}}
