[javascript] Handlebars/Mustache - Is there a built in way to loop through the properties of an object?

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.
