This is JavaScript not Java, however, there was only the option to select Java.

Design and implement a program that will allow us to determine the  length of time needed to pay off a credit card balance, as well as the  total interest paid.

The program must implement the following functions:

1. displayWelcome

This function should display the welcome message to the user explaining what the program does.

2. calculateMinimumPayment

This function calculates the minimum payment. It should take balance  and interest rate as arguments and return the minimum payment.

So the value you display for minimum payment is the value you get  from this method. Do not use a literal hardcoded value when you display  the minimum payment!

3. displayPayments

This function displays the actual payment schedule. It should take  the balance, monthly interest rate and minimum payment as arguments.

Use the 1500, 18% and 2% literal values below. 

See the sample execution below:

This program will determine the time to pay off a credit card and the interest paid based on the current balance,

the interest rate, and the monthly payments made.

Balance on your credit card: 1500

Interest Rate: 18

Assuming a minimum payment of 2% of the balance ($20 min)

Your minimum payment would be $ 30.00
