How does the code below work to output 16?

Question

for(i=4;i<8;i++) {
if(i==6) {
continue;
}
sum+=i;
}
alert(sum);

Answer 1

First : i=4 and the condition is i less than 8 which is true so i next is 5 then 6 will be skipped cause of if ...continue then 7 then end cause 8 is not less than 8 .the alert for the sum so 4+5+7 .

Answer 2

4 + 5 + 7 == 16.

Answer 3

6 is not added due to the continue statement.
