[Tutor] I don't understand this code

"wordList" is just a name that the function (getRandomWord) uses to
refer to
whatever values get passed to it. Remember that you don't have to put
your
list of words into a variable before you call the function.  You could
just
do this:-

getRandomWord('ant baboon badger bat bear')

...and it will work. Or consider having two or three variables:-

   words     = 'ant baboon badger bat bear'
   mylist    = 'left right backward forward up down'
   morestuff = 'run walk stand sit'

Naturally you can feed any of these into the function:-

   getRandomWord(words)
   getRandomWord(mylist)
   getRandomWord(morestuff)

You can think of "getRandomWord(wordList)" as a convenient
shorthand for:-

   wordList = words     
   getRandomWord(wordList)

Hope this helps
