bonus challenge question 

while ( i!==8){
  i= Math.floor(Math.random()*9); 
  text = text+ i + ' '    
}

this works but the answer on the video is

  i= Math.floor(Math.random()*9); 
while ( i!==8){
  text = text+ i + ' '  ; 
 i= Math.floor(Math.random()*9); 
}
  text = text+ i + ' ' ;

this seems there are more lines unnecessary. what would go wrong with first? if I am not right.

The final line on the video isn't accurately shown here, but the real one (combined with the line order inside the loop) prevents having an extra blank at the end of the line.

And if the value of "i" left over from the last section just happened to be "8", this loop would not run at all but the one in the video is guaranteed to show at least one number.
