Is it possible to declare variables in JavaScript inside an object declaration? I'm looking for something similar to

var myObject = {
    myLabel: (var myVariable)
};

instead of having to write

var myVariable;
var myObject = {
    myLabel: myVariable
};

EDIT

I want this in the context of Node.JS. This is what I have:

var server = {};
var database = {};
var moar = {};

module.exports = {
    server: server,
    database: databse,
    moar: moar
};

doStuffAsync(function callback() {
    // Populate variables
    server = stuff();
    database = stuff2();
});

• 4 why would you need that? – t.niese Commented Jan 15, 2013 at 14:13
• 1 myObject.myLabel would be undefined anyway, just like myObject.yourLabel, so what's the point? – danronmoon Commented Jan 15, 2013 at 14:15
• Edited question to clarify why I want this. – Randomblue Commented Jan 15, 2013 at 14:19
• why don't you pass module.exports to your doStuffAsync function so that you can set server and database directly at that object? – t.niese Commented Jan 15, 2013 at 14:22
• The only reason I can think of doing this is to save one line of code. If you're worried about the number of lines of code, look into minification instead of destroying your readability. – jbabey Commented Jan 15, 2013 at 14:26

If you want to scope a variable inside an object you can use IIFE (immediately invoked function expressions)

var myObject = {
    a_variable_proxy : (function(){ 
        var myvariable = 'hello'; 
        return myvariable; 
    })()
};

You can assign a value to a key directly.

If you now have:

var myVariable = 'some value';
var myObject = {
    myLabel: myVariable
};

you can replace it with:

var myObject = {
    myLabel: 'some value'
};
