Shorter way to write the while loop...?

Hi,

I think there's an even shorter way to write the while-loop:

let i; while (i!==8){ i=Math.ceil (Math.random()*9); text+=i+" "; };

Since you don't assign a value to i beforehand, it is generated at the beginning of the while-loop and stored in "text", so it is printed even if the first number is 8 (tested it).

You'll also need to initialize "text" before the loop (let text = "";) to avoid having it start with "undefined".

Being able to spot opportunities like this is evidence of your learning progress, good job! :+1:
