This small challenge comes from Chris Pine's "Learn to Program". Ensure that you read everything and click every link before starting the work.

Write a program which can imitate a Grandma who's hard of hearing and follows these constraints:

• If you don't input anything (just hit enter) she responds with WHAT?!

• If you ask a question with any lower-case letters, she responds with SPEAK UP, KID!

• If you talk to her in all upper-case letters, she responds with NO, NOT SINCE 1946!

• The first time you say GOODBYE! she says LEAVING SO SOON?

• The second time you say GOODBYE! she says LATER, SKATER! and the program exits.

HEY KID!
> hi, grandma
SPEAK UP, KID!
> I SAID HI, GRANDMA
NO, NOT SINCE 1946!
>
WHAT?!
> Goodbye!
SPEAK UP, KID!
> GOODBYE!
LEAVING SO SOON?
> GOODBYE!
LATER, SKATER!

• In your code you'll definitely need to use if and likely an elif and else.
• Also remember that input() is the "inverse" method of print() -- while print() outputs information to the terminal, input('command Prompt') captures information from the user by presenting a command prompt and allowing them to type input.
• If you have an infinite loop, how might you break out of it?

• In your code you'll definitely need to use if and likely an else if and else.
• This will be hard to do in the terminal with Node.js, because Node.js doesn't have a great built-in prompt.
• This is relatively easy to do in the browser with window.prompt, but you'll need to use an HTML file to run your javascript file.

For a little extra fun, try refactoring your code to use regular expressions.
