JavaScript proposal: destructuring assignment

That link is to a really old ES4 discussion. The proposal for ES6 is at <a href="http://wiki.ecmascript.org/doku.php?id=harmony:destructuring" rel="nofollow">http://wiki.ecmascript.org/doku.php?id=harmony:destructuring</a> and has now been incorporated in the draft ES6 spec.

A form of this will probably be in ES6:<p><a href="http://people.mozilla.org/~jorendorff/es6-draft.html#sec-11.13.1" rel="nofollow">http://people.mozilla.org/~jorendorff/es6-draft.html#sec-11....</a>

CoffeeScript implements this syntax, and, of course, it's extremely awesome.<p><a href="http://coffeescript.org/#destructuring" rel="nofollow">http://coffeescript.org/#destructuring</a>

I think this is a great proposal. I would be very happy to see destructuring assignment in JS. In every other language I've used that supports this (Erlang, Clojure) it is a big win.

This would be extremely handy. At the moment I'm sometimes even writing<p><pre><code> (function (a, b, c) {/**/}).apply(null, packed); </code></pre> to emulate destructuring.

Cool, if it gets widespread implementation.<p>Had to read a ways down to see an example to confirm, in simple terms, that this would mean you could make function calls such as:<p>( a, b, c) = f();<p>like you would in Perl / Python / Ruby. (not so good at decoding BNF while I'm sipping my first cup of coffee in the morning...)

This is something that's been in Firefox's JS way back since FF 2.0.<p><a href="https://developer.mozilla.org/en/New_in_JavaScript_1.7" rel="nofollow">https://developer.mozilla.org/en/New_in_JavaScript_1.7</a>

Seems like half of the comments are from 6 years ago, am I missing something?
