Hogan.js is a 2.5k Javascript templating engine developed at Twitter. Use it as a part of your asset packager to compile templates ahead of time or include it in your browser to handle dynamic templates. These javascript templating engine was written to meet three templating library requirements: good performance, standalone template objects, and a parser API.

Hogan.js was developed against the mustache test suite. That means you get variables, sections, lambdas, partials, filters, and everything else you’ve come to expect from mustache templating but only much, much faster.
