Prime Numbers Finder!

Write the web app to prompt accepting for a positive integer number

• If the entered text is not a positive integer number, then the web app will keep asking for a number until the valid positive integer is entered
• If the entered text is a positive integer, then the app will print prime numbers that are not greater than that given positive integer

Hint:

1. you may want to use loop with label
2. you may want to use array with push function
