I like how easy it was for me as an absolute beginner in coding, to pick up this new technology so quickly! It's great because you can write your code once then compile into JS which makes debugging much easier than if you were writing multiple files of different languages (C#/Javascript).
The syntax isn't too difficult but at first glance there are some things about its structure that may be confusing - however after using it awhile everything becomes second nature. If you're having any issues with learning or understanding what the compiler does when compiling from coffeescript to javascript please feel free to reach out via our github page https://github.com/coffeescripter/. We've been able to build tools very easily by combining Coffescripts functionality with other technologies we already have in place such as ReactJS.
