    Do not initialize a var to a val that's never used
    
    By initializing 'to' to a value, the code made it seem like that
    value mattered. But the value is overwritten in getWord().
    
    Further, now if 'to' is used before it is initialized, there might
    be a useful compiler warning that could point to a bug.
