6,606 PointsBONUS CHALLENGE in forLoops.js. Is it possible to get the exact same solution?
I tried the Bonus challenge with for loop, but the ending 8 wasn't in the string. Is it possible to get the same solution like with while and do..while loops? I tried with this :
for (let i = Math.floor(Math.random() *10); i !==8 ; i = Math.floor(Math.random() *10)) { text += i + ' '; }

So you need an extra statement to add it after the loop, just as is done in the video example. But with the code above, the variable "i" is not accessible from outside the loop, so you can substitute a literal instead:
text += "8";
Another way would be to build the string as part of the loop increment clause. Then the loop body could be left empty:
for (let i; i !== 8; i = Math.floor(Math.random() * 10), text += i + " ");

for (s = 0; s != 8 ;) { s = Math.floor(Math.random() * 9); text += s + ' '; }
