What is "htmlbars"

HTMLBars is a Web template system used in Ember.js, an open-source client-side JavaScript Web application framework. It is built on top of Handlebars, a superset of Mustache with a very similar syntax. The main difference between HTMLBars and Handlebars is that HTMLBars manipulates DOM nodes instead of strings which makes it easier to avoid code injections and cross-site scripting. This is inspired by the React.js Web framework that also doesn't use string-based templating but manipulates DOM nodes instead.
