Note: Remember. JavaScript is a prototype-based language.

var Module  = (function() {
    // declare private variables and/or functions
    var private_variable = "private variable content";
  
    var private_method = function(){
        console.log("private_method()");
        console.log("-> private method content");     
    }
    return {
        // declare public variables and/or functions     
        public_variable: "public variable content",
        public_method: function(){
            console.log("public_method()");
            console.log("->" + private_variable);     
        }
    };
})();
  
// Execution
console.log(Module.public_variable);
Module.public_method();
console.log("------------------------------");
console.log(Module.private_variable);
console.log(Module.private_method());
 
// Output
public variable content
public_method()
-> private variable content
------------------------------
undefined
Uncaught TypeError: Module.private_method is not a function
