Could someone please explain?

I know the answer is 12 but I don’t understand why: var a=0; for (k=1; k<=2; k++) { for (i=0; i<=5; i++) {} a++; console.log (a); }

The answer is 12 because you display the value of a variable each iteration so at first iteration a is 1 so it displays 1 on console then at the second iteration a is increased by 1 again so it displays 2 beside 1

Thanks @turtleshell. So the second loop isn’t factored?

The second loop is useless

Theres nothing inside the loop’s brackets for (i=0; i<=5; i++) {} <—
