How to configure an array iteration with mustache?

Question

I have an array like this:

array = [0, 1, 2, 3, 4, 5, 6, 7]

And 2 configuration variables:

var start = 2;
var count = 3;

And I want mustache to render the array exactly as the configuration demands to. My template is like this:

{#array}
    <p>{.}</p>
{/array}

I want my output to be this one:

<p>2</p>
<p>3</p>
<p>4</p>

How can I achieve that?

In your javascript you need to build subset of data using your start and count. For this you can use a library like underscore.js as shown below:

var array =  [0, 1, 2, 3, 4, 5, 6, 7];
var start = 2,  count=3;
var subset = _.range(start, start+count);

Then your Mustache template can be passed with the subset variable. You need to keep your Mustache templates as simple as possible.
