New in JavaScript 1.7 From MDC
Please note that this document is a work in progress. Some of the new features it covers are not implemented yet, so syntax may change.
JavaScript 1.7 is a language update introducing several new features, in particular generators, iterators, array comprehensions, let expressions, and destructuring assignment. It also includes all the features of JavaScript 1.6.
JavaScript 1.7 support is available in Firefox 2 Beta 1, as well as in current Minefield (trunk) builds.
The code samples included in this article can be experimented with in the JavaScript shell. Read Introduction to the JavaScript shell to learn how to build and use the shell.

看起來IE還沒支援到1.7版,所以想試看看的朋友們瀏覽器也要更新到Firefox 2才能跑囉~
