IO.js 服务器端 JS 引擎
IO.js 是为 V8 引擎编写的基于事件 IO 的实现。io.js可以说是彻底从NodeJS里分离出来的一条分支。既然是分支，io.js便也基本兼容NodeJS的各种API，连执行指令也依旧兼容Node的 node XXX （新指令是 iojs XXX ）。不过io.js采纳了最新版本的V8引擎，并也将会时刻跟进V8的更新，也因此我们可以轻松地在io.js上抢先使用那些JavaScript ECMA-262规范上的新特性。
io.js v3.3.0 发布，更新内容如下：
build: Add a --link-module option to configure that can be used to bundle additional JavaScript modules into a built binary (Bradley Meck) #2497
docs: Merge outstanding doc updates from joyent/node (James M Snell) #2378
http_parser: Significant performance improvement by having http.Server consume all initial data from its net.Socket and parsing directly without having to enter JavaScript. Any 'data' listeners on the net.Socket will result in the data being "unconsumed" into JavaScript, thereby undoing any performance gains. (Fedor Indutny) #2355
libuv: Upgrade to 1.7.3 (from 1.6.1), see ChangeLog for details (Saúl Ibarra Corretgé) #2310
V8: Upgrade to 4.4.63.30 (from 4.4.63.26) (Michaël Zasso) #2482
See https://github.com/nodejs/io.js/labels/confirmed-bug for complete and current list of known issues.
Some uses of computed object shorthand properties are not handled correctly by the current version of V8. e.g. [{ [prop]: val }] evaluates to [{}]. #2507
Some problems with unreferenced timers running during beforeExit are still to be resolved. See #1264.
Surrogate pair in REPL can freeze terminal. #690
process.send() is not synchronous as the docs suggest, a regression introduced in 1.0.2, see #760.
Calling dns.setServers() while a DNS query is in progress can cause the process to crash on a failed assertion. #894
url.resolve may transfer the auth portion of the url when resolving between two full hosts, see #1435.
