handlebars.js

问题 How can I call a handlebars block helper from another helper in ember.

问题 I know, I don't need it, but I think I actually do. I want to have a valid JS code rendered by handlebarsjs before it is even rendered. The JS minification tools just minify valid JS files and minifying on the fly increases processing time.

The handlebars helper is: function json(context) { return JSON.stringify(context); }
