JSRender

What is JsRender?
Many development platforms use templates to reduce code and simplify maintenance, and HTML5 and JavaScript are no exception. JsRender is a JavaScript library that allows you to define a boilerplate structure once and reuse it to generate HTML dynamically. JsRender brings a new templating library to HTML5 development that has a codeless tag syntax and high performance, has no dependency on jQuery nor on the Document Object Model (DOM), supports creating custom functions and uses pure string-based rendering.

Why Templates?
Using templates with JavaScript reduces and simplifies code. Without templates, adding a series of list items and other HTML elements for a set of data might require manipulating a browser’s DOM. This is where templating using a plug-in such as JsRender can be quite useful to do the heavy lifting.
