In Javascript Write down codes to enter as many numbers as you want until you enter a zero. Then, the app will display the average of all the numbers you've entered, excluding the zero. If the first number you've entered is a zero, then display that the app cannot calculate the average because you haven't entered any number other than the zero.

For example, if you enter the following numbers:

• 7
• 4
• 6
• 2
• 2
• 0

The average is 22 / 5 or 4.4.
