Question

I got the code below from a Javascript Library:

function func_1()
{
    if ( null == decimal ) 
    {
        return dPR || (dpr(2) ? 2 : dpr(1.5) ? 1.5 : dpr(1) ? 1 : 0);
    }
}

I’m particularly interested in the code inside the if statement.

How else can I write this so that it’s easier to read?! As it is now I can’t understand it.

Thanks.

Answer 1

it’s equivalent to:

if (dPR) {
    return dPR;
} else {
    if (dpr(2)) {
        return 2;
    } else {
        if (dpr(1.5)) {
            return 1.5;
        } else {
            if (dpr(1)) {
                return 1;
            } else {
                return 0;
            }
        }
    }
}
