Subscriber pattern? how do i access methods from submodule 1 from inside submodule 2

gistfile1.txt

var superModule = (function(){
// global state
return {
    submodule1:{
    // contains some internal state
    // contains methods
    }, 
    
    submodule2:{
    // contains some internal state
    // contains methods
    }
}
})(); 

superModule.submodule1.init(); 

// OR THIS IMPLEMENTATION THAT USES MODULE PATTERNS IN SUB-MODULE TOO!
// or the submodule can be closues for private internal state
var superModule = (function(){
// global state
return {
    submodule1: (function(){
        // internal state
        return {
            // methods
        }
    })(), 
    
    submodule2: (function(){
        // internal state
        return {
            // methods
        }
    })()
})();
