Just experimenting with publishing a package

/***********************************************************************
Declare a function named partyPlanner(). When invoked the partyPlanner function will
return an object that represents a party. The object returned by partyPlanner will
have a property named guestList that will point to an array. 

The object returned by partyPlanner will additionally have two functions:
1. throwParty() - which will return a different string depending on the number 
 guests on the guestList. 
  A. If there are no guests the returned string request more guests
  B. If there are guests on the guestList the returned sting will include those 
  guest's names.

2. addToGuestList(name) - will add a name to the party object's guestList property


Closely look at the examples below for more information on each method:

Examples:
const party = partyPlanner();

console.log(party.throwParty()); // prints "gotta add people to the guest list"

party.addToGuestList("James");
console.log(party.throwParty()); // prints "Welcome to the party James"

party.addToGuestList("Alvin"); 
console.log(party.throwParty()); // prints "Welcome to the party James and Alvin"

Example 2:
const party2 = partyPlanner();
console.log(party2.throwParty()); // prints "gotta add people to the guest list"

party2.addToGuestList("Lucy");
console.log(party2.throwParty()); // prints "Welcome to the party Lucy"
