The result of the code is 9 but I don't understand why. Please someone should help explain to me why?

Question

var count = 6, sum = 0;
while(count>0) {
sum+=3;
count-=1;
if(count==3) {
count = 0;
}
}
document.write(sum);

Answer 1

Thanks ~ swim ~, that explanation was clear and precise

Answer 2

Count = 6, 5, 4 Sum = 3, 6, 9 😊

Answer 3

Ez, to those who still don't understand, it's looping count -= 1 simply by subtracting 1 and setting it as the new variable value, until it reaches 3 from 6... Which is three times. In those three times the code is also adding 3 to sum that was originally 0... And 0 plus 3 three times makes 9. Hope that helps.
