how do I cut up a number like 281 in javascript

what do you mean by cut up?

So I will have

from 281, I get

a=2, b=8, c=1

Can you please explain the code.
thanks for your help

i am simply removing the last digit the from variable in every iteration of the while loop and storing that last digit in the digits array

Kindly tell me if it works or not

Yes it works - I just trying to understand your code here.

Why did you use 10 here?

digits[ digits.length ] = val%10;
  val = val /10;
