How to iterate a JSON array using Mustache

You want "shows" to be in a hash in order to properly iterate:

var shows={"shows":[        
        {"title":"Strawberry Shortcake","description":"A show about a cake","video":"none","category":"chilren"},
        {"title":"Vanilla Ice","description":"A show about a ice","video":"none","category":"adult"}
]};

var template="{{#shows}}{{.}}{{/shows}}";

var html=Mustache.render(template,shows);

document.write(html);

This will have the desired effect of producing your template multiple times.

UPDATE

To your question on Lambdas. I just looked this up in the manual. I think it covers what you were asking about:

When the value is a callable object, such as a function or lambda, the object will be invoked and passed the block of text. The text passed is the literal block, unrendered. {{tags}} will not have been expanded - the lambda should do that on its own. In this way you can implement filters or caching.

Template:

{{#wrapped}}
  {{name}} is awesome.
{{/wrapped}}

Hash:

{
  "name": "Willy",
  "wrapped": function() {
    return function(text) {
      return "<b>" + render(text) + "</b>"
    }
  }
}

u can do like this:

var shows=[        
        {"title":"Strawberry Shortcake","description":"A show about a cake","video":"none","category":"chilren"},
        {"title":"Vanilla Ice","description":"A show about a ice","video":"none","category":"adult"}
];

var template="{{#.}}title:{{title}},video:{{video}}{{/.}}";

var html=Mustache.render(template,shows);

document.write(html);
