The basics of Handlebars

Handlebars is a really simple and easy-to-use templating framework. Let's go through and explore the basic syntax of writing a Handlebars template.

Binding an object to the template

Let's assume the following JavaScript object is passed to a Handlebars template:

var model = {

};

The template file itself will contain the following markup:

<div>
  Hello {{ name }}!
</div>

This file will render to a browser in the following way:

Hello World!

var model = {
  name: 'World',
  description: 'This will only appear because its set.'
};

<div>
   Hello {{ name }}!<br/><br/>
  {{#if description}}
     <p>{{description}}</p>
  {{/if}}
</div>
