-> CoffeeScript 2 generates JavaScript that uses the latest, modern syntax.
-> The runtime or browsers where you want your code to run might not support all of that syntax.
-> In that case, we want to convert modern JavaScript into older JavaScript that will run in older versions of Node or older browsers; for example, { a } = obj into a = obj.a.
-> This is done via transpilers like Babel, Bublé or Traceur Compiler.
+> CoffeeScript 2 使用最新的句法生成 JavaScript。
+> 代码运行所在的运行时或浏览器有可能无法支持全部相关句法。
+> 这种情况下，新的 JavaScript 句法将被转换为旧的 JavaScript 句法，以便在较低版本 Node 环境或浏览器中运行这些代码。比如将 { a } = obj 转换为 a = obj.a.
+> 这个转换的过程是由一些诸如 Babel, Bublé or Traceur Compiler 等转换工具完成的。
