Could you explain?

Question

var count=0;
for(var i=0; i<=6; i++){
if(i==3){
i=5;
continue;
}
count++;
}
document.write(count);

//output is 4
//could you explain how did we get that output?

Answer 1

After 1. iteration: i=1; count = 1
After 2. iteration: i=2; count = 2
After 3. iteration: i=3; count = 3
After 4. iteration: i=6; count = 4

After the i=3 iteration the if clause will be used. So i=5 and after the continue the for loop will increase i to 6. After that the for loop condition isn't true anymore. :)

Answer 2

i=0 --> count++
i=1 --> count++
i=2 --> count++
i=3 --> i=5
i=6 --> count++

Answer 3

3 was skipped which means counter incremented 4 times
