CoffeeScript 1.11.0 发布，脚本语言

CoffeeScript 1.11.0 发布了。

offeeScript这一门编程语言构建在JavaScript之上，其被编译成高效的JavaScript，这样你就可以在web浏览器上运 行它，或是通过诸如用于服务器端应用的Node.js一类的技术来使用它。编译过程通常都很简单，产生出来的JavaScript与许多的最佳做法都保持了一致。

此次更新内容：

• CoffeeScript now supports ES2015 import  and  export  syntax .

• Added the -M, --inline-map flag to the compiler, allowing you embed the source map directly into the output JavaScript, rather than as a separate file.

• A bunch of fixes for yield :

• yield return can no longer mistakenly be used as an expression.

• yield now mirrors  return in that it can be used stand-alone as well as with expressions. Where you previously wrote  yield undefined , you may now write simply  yield . However, this means also inheriting the same syntax limitations that  return has, so these examples no longer compile:

  doubles = ->
    yield for i in [1..3]
      i * 2
  
  six = ->
    yield
      2 * 3

• The JavaScript output is a bit nicer, with unnecessary parentheses and spaces, double indentation and double semicolons around yield no longer present.

• Improved several error messages.

• Just like undefined compiles to  void 0 ,  NaN now compiles into  0/0 and  Infinity into  2e308 .

• Bugfix for renamed destrucured parameters with defaults. ({a: b = 1}) -> no longer crashes the compiler.

• Improved the internal representation of a CoffeeScript program. This is only noticeable to tools that use CoffeeScript.tokens or  CoffeeScript.nodes . Such tools need to update to take account for changed or added tokens and nodes.

• Several minor bug fixes.
