Hey guys im not sure to understand this one.. you can help? What is the output of this code? var sum=0; for(i=4; i<8; i++) { if (i == 6) { continue; } sum += i; } document.write(sum); 1

At the beginning:
sum = 0
i = 4
First iteration:
sum += i --> sum = 0 + 4 --> sum = 4
i++ --> i = 4 + 1 --> i = 5
Second iteration:
sum += i --> sum = 4 + 5 --> sum = 9
i++ --> i = 5 + 1 --> i = 6
Third iteration:
i == 6 is true, so continue is triggered, skipping the rest of the interation, so i is not added to the sum
i++ --> i = 6 + 1 --> i = 7
Fourth iteration:
sum += i --> sum = 9 + 7 --> sum = 16
i++ --> i = 7 + 1 --> i = 8
Loop ends:
i<8 is false, so the loop ends
sum = 16
