Handlebars/Mustache – Is there a built in way to loop through the properties of an object?

As the title of question says, 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
}

?
