Modern web applications are now increasingly leveraging the power of JavaScript to create dynamic interfaces. While most frameworks allow you to manipulate DOM, however, managing extensive changes in the document with each change of the view is somehow tricky. This is where you should use JavaScript templating language like Handlebars.js.

Handlebars.js is a JavaScript based templating language that allows you to build semantic templates. Handlebar templates look like regular HTML with embedded handlebar expressions. So the code is easy to understand, learn and use. It also allows you to write your code in the fashion of block expression.
