What type of design pattern follows this JavaScript code?

Recently I encountered with following type of JavaScript code

var Person = {
 vars : {
    FirstName:'',
    LastName :'',
    Gender: ''
 },
 Save:function(){
   //Some JavaScript logic here
  },
 GetById: function(id)
 {
  //Some JavaScript logic here
}
}

What do you call it?

Modular JavaScript Programming or other design pattern?
