Let me first say, {{}}. now you know the entire Mustache templating language (almost)
Mustache.js is a JavaScript port of the Ruby templating language Mustache. I use Mustache.js on the front-end and in the back-end with node.js
Mustache.js is crazy simple, if you can grasp the power of Mustache.js you can be doing client-side and server-side templating using the same templates!
Protip : {{{}}} - that is a triple mustache, it is just like a regular mustache except it will NOT escape HTML
