A very simple alternative solution without a while loop.

Greetings.. I tried the following JS script before watching the lecture to the end. It is quite basic stuff but it is still working. Have a beautiful day.

function lookFor() {
 search = prompt('Search for a product in the store.');

      if (search === 'quit') {
        print('Have a nice day.')
      }

      else if (search === 'list') { 
        var listIt = inStock.join(', ');
        print(listIt);
      }

      else if (inStock.indexOf(search) !== -1) {
        print('Yes, we have ' + inStock[inStock.indexOf(search)] + ' in the store.');
      }

    else {
      print('We do not have ' + search + ' in the store.');
    }
}

lookFor();

Thanks Shez. I am not asking anything particular. I just wanted to share a simpler version without a loop.

I tested your code and found only one problem, it doesn't repeat if you searched for Milk for instance, the code ends after the first message is written and doesn't prompt the user for more input. Cool method though, but I think for this a loop is in order, either that or a lot of lines calling the function, although even a lot of lines calling the function doesn't work properly because it doesn't break away from the next function call if 'quit' is written.

You also probably should convert search .toLowerCase()
