Why is 0 the value of the code below when "sum+=i" means that the iterations of the loop are to be added?

Question

var sum=0;
for(var i=1;i<=10;i++) {
if(i%5===0 && i%3===0) {
sum+=i
}
continue;
}
document.write(sum);

Answer 1

The loop goes all the way up to ten. The first number evenly divisble by both 5, and 3 is 15.

Answer 2

@Airree oh 🤔 so do you mean that if the if statement contains (i%4===0 && i%3 === 0), we would still have 0 as the output?

Answer 3

Mofey
i%anynumber === 0 is going yo be true, only if i is divisble by the number evenly. Therefore, if you have two statements like this, it will have to be evenly divisible by both numbers.

Answer 4

Alright Jax, thanks for the explanation

Answer 5

Jax so do you mean that the output is zero because there's no number divisible by 5 and 3 below the numbers of 10?

Answer 6

Yes, the first number divisible by 3 and 5 is 15.
