Question

Would someone mind converting this line of ternary code to if/then statements. I understand ternary, but am not able to get syntax errors to go away when I convert to if/then. This is the only line of my homework I had to borrow and I’d like to make it into if/then so that I can comment on it and understand it better myself.

Original:

return n == null || isNaN(n) ? 0 : n;

My attempt:

return n == null || if(isNaN(n)){return 0;}else{return n;}

Answer 1

You have to move the return and have a separate one for the if and the else:

if(n == null || isNaN(n)){
    return 0;
}else{
    return n;
}
