Defining iterative block helpers in Meteor 0.8

Question

Until version 0.8 it was possible to use the regular Handlebars way for defining iterative block helpers such as the popular each_with_key, defined, e.g., here

Answer 1

And just as I was about to give up, I figure it out. It's in fact easier and prettier now in 0.8 than it was before. The following seems to work great:

JS:

UI.registerHelper('addKeys', function (all) {
    return _.map(all, function(i, k) {
        return {key: k, value: i};
    });
});

HTML:

{{#each addKeys obj}}
<div>
   {{key}}: {{value}}
</div>
{{/each}}
