There is various way to define a function. It is totally based upon your requirement. Below are the few styles :-

1. Object Constructor
2. Literal constructor
3. Function Based
4. Protoype Based
5. Function and Prototype Based
6. Singleton Based

Examples:

1. Object constructor

var person = new Object();

person.name = "Anand",
person.getName = function(){
  return this.name ; 
};

2. Literal constructor

var person = { 
  name : "Anand",
  getName : function (){
   return this.name
  } 
} 

3. function Constructor

function Person(name){
  this.name = name
  this.getName = function(){
    return this.name
  } 
} 

4. Prototype

function Person(){};

Person.prototype.name = "Anand";

5. Function/Prototype combination

function Person(name){
  this.name = name;
} 
Person.prototype.getName = function(){
  return this.name
} 

6. Singleton

var person = new function(){
  this.name = "Anand"
} 

You can try it on console, if you have any confusion.
