About Sonarlanguage is what dongdong, here is not described, if you are interested in it, please go to the previous essay open Source: angularjs example--sonar Project use language map. Here is a recent practice version of learning Coffeescript.
Coffeescript is a concise, JavaScript-based preprocessor language that can be statically compiled into JavaScript, which is primarily influenced by Ruby and Python and is now used for many rails and node projects. Coffeescript is not a hyper-set of JavaScript, nor is it a complete substitute. Coffeescript is a little bit:
Less, more compact, and clearer code
By avoiding and changing the use of bad parts of JavaScript, leaving only the essence, the code to reduce the error rate, easier to maintain
Best practices in JavaScript are adopted in many common patterns implementations
The JavaScript code generated by Coffeescript can be completely detected by JSLint
Many do not want to say so much, here is mainly a brief introduction, Coffeescript's LIANBI example.
The code is as follows:
App = Angular.module (' app ', []). Value ("$host", "http://nemo.sonarsource.org"). Facto
Ry ("$requestUrl", ($host)-> "#{$host}/api/resources"). Factory ("$dynamicColor", ($host)->
[R,g,b] = [10,10,0] {getcolor:->
[R,g,b] = [(r+100), (g+400), (b +)] "##{(r + 256 * g + 65536 * b). toString 16}"
, Reset:-> [r,g,b] = [10,10,0]
};
