Also, style guides with 2 spaces indention are also good and wide-spread
(other things are the same as described in the link which Mark gave --
this is Java's style guide by the way).

I like http://javascript.crockford.com/code.html , though I disagree
with leaving a space between "function" and "(" for anonymous functions.
Since function name is optional in case of an expression, a space after
the function may make sense.
function foo() {}
function () {} -- just name disappeared, all the other the same.
Or, an analogy -- you put a space after some statements which are
followed by the parenthesis, right? E.g.:
while (true) {}
if (false) {}
the same with function.
However, of course it's just a local style guides. E.g. in Erlang, space
is not put (as usually and in code of standard library) for function
expressions as in your variant:
Double = fun(X) -> X * X.
(fun(X) X * X)(2)
OTOH there, in contrast with JS, `fun`s don't have names.
P.S.: Back to topic, the thing which I personally don't like is to put a
colon on a new line, as used in Node.js often:
var a = 10
, b = 20
, c = 30;
Of course it has advantages, e.g. for commenting one line, but literally
looks odd for me.
But in general ECMAScript has no style guide. As well as there is no
such language as ECMAScript (I mean, it's the sample implementation
which is called ECMAScript), and all others are just local style guides.
Usually that's said, either Java's style guide is used, or the same but
with 2 spaces.

I was wondering if a canonical guide for ECMAScript style and
conventions exists - specifically I'm curious to find out what the
historic precedence, rules and reasoning behind the capitalization
of constructors and built-in objects, ie. Array or Math. Even
_more_ specifically, there exists a fairly common convention that
first letter capitalization is generally reserved for constructors
that expect to be paired with "new"... obviously this is not a
hard rule, but I'm curious if any documentation or articles exist
regarding the subject.
Thanks!
