Is there a Mustache / Handlebars way of looping through an object properties?

So with

var o = {

  bob : 'For sure',

  roger: 'Unknown',

  donkey: 'What an ass'

}

Can I then do something in the template engine that would be equivalent to

for(var prop in o)

{

    // with say, prop a variable in the template and value the property value

}

?

Built-in support since Handlebars 1.0rc1

Support for this functionality has been added to Handlebars.js, so there is no more need for external helpers.

How to use it

For arrays:

{{#each myArray}}

    Index: {{@index}} Value = {{this}}

{{/each}}

For objects:

{{#each myObject}}

    Key: {{@key}} Value = {{this}}

{{/each}}

Note that only properties passing the hasOwnProperty test will be enumerated.
