1、最近看别人写的js代码中有 FIXME 标识，不知其含义。bing了一下，并未找到对 js 这种标识的特殊说明，大多都是说 eclipse 中特殊的注释，但是看到好东西，还是要记录一下滴。
2、总结：代码中TODO、FIXME、XXX等注释单词，特殊含义：
TODO: No problem, but addtional code needs to be written (usually when you are skipping something)
注释处有未编写的功能代码，一般会简略描述未实现的功能。
FIXME: This works, sort of, but it could be done better. (usually code written in a hurry that needs rewriting)
注释处代码需要修正，甚至代码是错误的，不能工作，需要修复，如何修正会在说明中简略描述。
XXX: Warning about possible pitfalls, can be used as NOTE:XXX:
注释处代码虽实现了功能，但实现的方法有待商榷，希望将来能改进，待改进的地方会在说明中简略描述。
NOTE: （描述功能）Description of how the code works (when it isn’t self evident)
HACK:（ 填坑）Not very well written or malformed code to circumvent a problem/bug. Should be used as HACK:FIXME
BUG: （挖坑）There is a problem here.
