So, I have the code, its not done, but all i want it to do is display one alert box if I write the word \'help\', and say something else if anything else is entered.
The problem is here:
if (reply === 'help' || 'Help') // <-- 'Help' evaluates to TRUE // so condition is always TRUE
The equality operator doesn't "distribute", try
if (reply === 'help' || reply === 'Help')
