推荐答案

您可以关注此问题： https： //code.google.com/p/v8/issues/detail?id=2700

目前（截至02.05.2014）已实施箭头功能并等到此功能将在第8版中登陆： https://codereview.chromium.org/160073006/

Currently (as 02.05.2014) arrow functions have been implemented and waiting until this functionality will be landed in v8: https://codereview.chromium.org/160073006/

之后我们需要等待，直到带有箭头功能的v8版本被集成到Node.JS中。您可以在那里关注Node.JS更改日志： https://github.com/joyent/node/blob/master/ChangeLog （搜索v8：升级到....）

After then we'll need to wait, until v8 version with arrow function would be integrated into Node.JS. You can follow Node.JS changelog there: https://github.com/joyent/node/blob/master/ChangeLog (search for "v8: upgrade to ....")
