Could someone explain this to me? I don't understand this one.

Question

var sum=0;
for(i=4; i<8; i++) {
if (i == 6) {
continue;
}
sum += i;
}
document.write(sum);

why does the result of this code is : 16??

Help me pleaseeee....

Answer 1

Variable i assumes values 4, 5, 6, 7 for each iteration which executes loop body. If i is 6, we proceed to the next iteration without doing anything, else, the program adds i to the sum variable. Hence

sum is 4+5+7

16

Answer 2

Continue keyword skips the rest of the code inside the loop and the control is transferred back to the beginning of the for loop. So when i=6 the 'sum' is not updated. The values added up are 4,5,7 and their addition is 16.
