DivisionStringified.js

/* Using the JavaScript language, have the function DivisionStringified(num1,num2) 
take both parameters being passed, divide num1 by num2, and return the result as a 
string with properly formatted commas. If an answer is only 3 digits long, return 
the number with no commas (ie. 2 / 3 should output "1"). For example: if num1 is 
123456789 and num2 is 10000 the output should be "12,345".  */
