How come the value of the code equals 337?

Question

function mlt(a, b) {
if(!a && b)) {
return 0;
} else if(b == 1 ) {
return a;
} else {
return (a + mlt(a, b - 1));
}
}
document.write(mlt(3, 11));
document.write(mlt(7, 1));

Answer 1

You left out the first line.

Basically what this function does, is multiplies the numbers together. If you check it with 3 and 11, it will just add 3 11 times together. The same with 7 and 1, it returns 7 times 1

Answer 2

Airree yeah I did leave out the first line but I've updated the question now
