Question 1

What is Handlebars.js and why should I use it?

Accepted Answer

Handlebars.js is a popular templating engine for JavaScript. It helps developers to create and render semantic templates effectively. The main advantage of using Handlebars.js is that it allows for cleaner and more maintainable code by separating the HTML structure from the JavaScript logic.

Question 2

What are Handlebars expressions and how do they work?

Accepted Answer

Handlebars expressions are placeholders for data within an HTML template. They are enclosed by double curly braces {{ }} and are replaced by the relevant data when the template is rendered. These expressions can include variables, HTML elements, or even Handlebars helpers that transform or manipulate the data before displaying it.

Question 3

What is the difference between Handlebars and other templating engines like Mustache?

Accepted Answer

Both Handlebars and Mustache are logic-less templating engines, but Handlebars extends Mustache functionality by providing support for block expressions, custom helpers, and partials. This makes Handlebars more powerful and flexible, allowing developers to create more complex templates and maintain better code organization.

How do I compile and render a Handlebars template?

Question 5

Can I include HTML within Handlebars expressions?

Accepted Answer

Yes, you can include HTML within Handlebars expressions. However, by default, Handlebars escapes any HTML characters to ensure security against Cross-site Scripting (XSS) attacks. To render HTML content without escaping it, use triple curly braces {{{ }}} instead of double curly braces {{ }}. Keep in mind that you should only do this for trusted content to avoid potential security risks.
