CoffeeScript vs HAML: What are the differences?

CoffeeScript: Unfancy JavaScript. CoffeeScript is a little language that compiles into JavaScript. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way; HAML: HTML Abstraction Markup Language - A Markup Haiku. 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.

CoffeeScript and HAML belong to "Languages" category of the tech stack.

"Easy to read" is the primary reason why developers consider CoffeeScript over the competitors, whereas "Clean and simple" was stated as the key factor in picking HAML.

CoffeeScript and HAML are both open source tools. It seems that CoffeeScript with 15.2K GitHub stars and 1.99K forks on GitHub has more adoption than HAML with 3.44K GitHub stars and 544 GitHub forks.

Code School, Zaarly, and thoughtbot are some of the popular companies that use CoffeeScript, whereas HAML is used by Kickstarter, Code School, and StackShare. CoffeeScript has a broader approval, being mentioned in 364 company stacks & 170 developers stacks; compared to HAML, which is listed in 113 company stacks and 40 developer stacks.
