HAML vs Handlebars.js: What are the differences?
- Syntax: HAML uses indentation-based syntax while Handlebars.js uses curly braces and double brackets for templating.
- Conditional Statements: HAML supports conditional statements like if/else whereas Handlebars.js primarily focuses on looping through data.
- Interpolation: Handlebars.js supports data interpolation using {{ }} whereas HAML uses a combination of !{} and - to output data dynamically.
- Helper Functions: Handlebars.js allows the creation and usage of custom helper functions to manipulate data whereas HAML doesn't have a built-in mechanism for this.
- Whitespace Control: HAML has significant whitespace control for clean and readable code output whereas Handlebars.js is less strict in this aspect.
- Data Binding: Handlebars.js implements a two-way data binding mechanism for synchronizing data between the view and model, a feature not found in HAML.
In Summary, HAML and Handlebars.js differ in syntax, conditional statements, interpolation methods, handling of helper functions, whitespace control, and data binding approaches.

@All: I am searching for the best template engine for .NET. I started looking into several template engines, including the Dotliquid, Handlebars.js, Scriban, and Razorlight. I found handlebar a bit difficult to use when using the loops and condition because you need to register for helper first. DotLiquid and Scriban were easy to use and in Razorlight I did not find the example for loops.
Can you please suggest which template engine is best suited for the use of conditional/list and looping and why? Or if anybody could provide me a resource or link where I can compare which is best?
Thanks In Advance

I like Handlebars, it's very mature... some would say-- outdated.
Handlebars loops are done via {{#each myList}}. Read the docs! https://handlebarsjs.com/guide
Remember, don't put logic in your templates! Keep this layer simple. Sorry to hear you have to use dotNet.

What is HAML?
Haml is a markup language that’s used to cleanly and simply describe the HTML of any web document, without the use of inline code. Haml functions as a replacement for inline page templating systems such as PHP, ERB, and ASP. However, Haml avoids the need for explicitly coding HTML into the template, because it is actually an abstract description of the HTML, with some code to generate dynamic content.
What is Handlebars.js?
Handlebars.js is an extension to the Mustache templating language created by Chris Wanstrath. Handlebars.js and Mustache are both logicless templating languages that keep the view and the code separated like we all know they should be.

Pug
This project was formerly known as "Jade." Pug is a high performance template engine heavily influenced by Haml and implemented with JavaScript for Node.js and browsers.
YAML
A human-readable data-serialization language. It is commonly used for configuration files, but could be used in many applications where data is being stored or transmitted.
JavaScript
JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
Python
