Syntax for variables within a namespace

[gimme_this_gimme_that@yahoo.com]

var BN = {
foo: function() {
alert("hello world");
},
z: function() {
alert("hello world");
},
}

I would like to add a member moo to BN whose definition is

var moo = {"a":"A","b","B "};

How do I do it?

Thanks

The right hand side of your assignment to moo isn't valid Javascript syntax, so
there is no way to add it to BN. What are you really trying to do?

moo is a hash.

var moo = {"a":"A","b":"B "};

Variable names starting with capital letters are usually reserved for
constructors. That last comma is a syntax error.

Another stray comma, and property names don't need to be quoted in
object literals:

var moo = {a:"A", b:"B"};

How do I do it?

To add a property moo to the object BN:

BN.moo = {...};

Re: Syntax for variables within a namespace

Can you make the assignment withing the braces?

As in

BN = {
// create moo here
}

ACK

That last comma is a syntax error.

Strictly adhering to the ECMA-262 Ed. 3 grammar, yes. Considering the
Conformance section of ECMA-262 (all editions so far), no.

[...] property names don't need to be quoted in object literals:

Not quite correct.

var moo = {a:"A", b:"B"};

It is only possible to omit the quote characters or apostrophes around
the property name here because `a' and `b' are identifiers.

var BN = {
foo: function() {
alert("hello world");
},
z: function() {
alert("hello world");
},
moo: {"a": "A", "b": "B"}
}

or you could have augmented your original BN:

BN.moo = {"a": "A", "b": "B"};

One should note, that IE (6) has it's problems with this extra comma. FF
and Opera (and suppose others) not.

The Conformance section is there to permit extra features. It's not
there to permit random typing errors. A certain amount of common sense
is assumed, of browser designers as well as of web designers.
