I need help with console output how to do with JavaScript.

I would like to know what is the console output would be... 

function ad(s){
    var j;j=fst(s);
    j+=0.01;
    return j/100;
}

function withtax(a){
    var j,i;i=a>=10?'PA':'';/*j=ad(i);*/a*=1+ad(i);return Math.round(a);
}

function fst(m){
    switch(m) {
        case 'NJ': return 7.52;
        case 'PA' : return 9.99;
        case 'DE': return 3.19;
        case 'CA': return 8.01;
        default:
        return 0;
     }
}

function dnoth(x){
    var i;
    for(j=0;j<5;j++) {
        j%2==0?i*=j:i-=j;
    }
    return –i;
}

I was copy and paste into my console. How would you do that because I got an error on console inspect? it said uncaught synataxError: unexpected token ILLEGAL. I was trying with http://jsfiddle.net/ and it was not working at all..

you are having a copy / paste issue. When pasting the current code for the dnoth function you get

function dnoth(x){
    var i;for(j=0;j<5;j++) { 
        j%2==0?i*=j:i-=j; 
    } 
    return –i; 
}

instead of

function dnoth(x){
    var i;for(j=0;j<5;j++) { 
        j%2==0?i*=j:i-=j; 
    } 
    return -i; 
}

Here is a link the working example: https://jsfiddle.net/p84x0c58/

I had a interview in couple of days ago and I took the snapshot. I found out the result last Friday and I failed the test and I learned a lot new of these questions. The question was intermediate to advance level of JavaScript.
