Editing JavaScript template language shootoff This edit will create a new revision. Your details (optional) Name Email (won’t be displayed; might be used for Gravatar) URL Test case details Title * Published (uncheck if you want to fiddle around before making the page public) Description (in case you feel further explanation is needed)(Markdown syntax is allowed) A limited comparison of some popular JavaScript templating engines on a short template: ***6 header tags, and 10 list items***. Compared templating engines: - [Mustache](http://mustache.github.com/) - [js render (replacing jQuery templates)](https://github.com/BorisMoore/jsrender/) - [Kendo UI Templates](http://demos.kendoui.com/templates/index.html) - [Handlebar](http://www.handlebarsjs.com/) - [Resig Micro-Templating (modified)](http://ejohn.org/blog/javascript-micro-templating/) - [Underscore JS](http://documentcloud.github.com/underscore/) - [jQote2](http://http://aefxx.com/jquery-plugins/jqote2/) - [doT](http://http://olado.github.com/doT/) *Note: When adding a new test, please ensure that your test returns the same HTML string (or equivalent DOM fragment) as the others.* Please try to refrain from making this a soapbox to push your particular technology, it's more impressive when the results speak for themselves.
