Why Haml?
Haml (HTML Abstraction Markup Language) is a whitespace-sensitive templating engine for Ruby, commonly used in Rails. It replaces inline HTML with clean, indented syntax that’s easier to read and maintain.
Benefits of Haml include:
- Cleaner and shorter syntax compared to ERB
- Improved readability and maintainability
- Faster front-end templating for Rails developers
Haml is used by many Ruby shops and developers for rapid Rails development, including Unspace Interactive.
