Is there a way in mustache to render a block if a section is present without iterating?

Question

I have a section with a header that I want to show only if the array is populated, something like this:

<h1> These are the elements in the array </h1>
<ul>
    {{#myArray}}
    <li>{{name}} - {{value}}</li>
    {{/myArray}}
</ul>

How can I render the <h1> only if myArray is populated?

If i put it inside the # section it is rendered once for every element in the array, which is not what i want.

What's the correct way to do this?

Answer 1

{{#myArray.length}}
     <h1> These are the elements in the array </h1>
{{/myArray.length}}

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

DEMO

In terms of PHP:

{{#myArray.0}}
     <h1> These are the elements in the array </h1>
{{/myArray.0}}
