Templatr – JSON to HTML Template Engine

Templatr is free, JSON-powered, fully client-side, library-independent, fast and responsive templating engine for HTML. It’s easy to define and use templates are parsed on the client and cached for later use. Ideally it can be used for AJAX-driven applications to reduce the requests to the server, as you can just get the data for the server and parse and render it entirely on the client by Templatr.
