Javascript notation. Need help understanding this declaration

I have inherited a block of code and I need confirmation that I'm understanding it correctly. I'm (perhaps obviously) not a javascript expert but I'm trying. I just need some help understanding exactly what the block of code below is doing:

SG_VERSION = "2.1", fss = [], allAni = {}, SG_PATH = "", sgZoom = 1, SG = function() {

  function complete() { ... }

  function Game() { ... }

  function win() { ... }

  function resize() { ... }

My understanding is that SG_VERSION is an 'object' with some member variables and a big method called SG, that itself has member functions? But doesn't SG_VERSION need a 'var' somewhere?

Thanks for any insights. I appreciate any and all help however simple it may seem.

Based on your snippet, these seem to be global variables (assuming you didn't miss out an initial var and that they are not declared inside an outer function() {}),

SG_VERSION = "2.1" // probably a string version representation
fss = [] // empty array initialization
allAni = {} // empty object initialization
SG_PATH = "" // probably to hold string values representing a PATH
sgZoom = 1 // numeric zoom level?
SG = function() {} // a function that seems to be intended for use as a class containing "private" functions complete(), Game(), win() and resize().

For the last variable SG = I think you've missed out a closing brace in your copy/paste

It will be more readable if written like this:

var SG_VERSION = "2.1"; 
var fss = []; 
var allAni = {};
var SG_PATH = ""; 
var sgZoom = 1;

var SG = function() {...};

function complete() { ... }

function Game() { ... }

function win() { ... }

function resize() { ... }
