Use Multiple Conditional Operators 2018.08.1

Why my code wrong???

Your code so far


function checkSign(num) {
    return (num > 0) ? “positive” : (num < 0) ? “negative” : “zero”;
}

checkSign(10);

When using " instead of ,
it works.

Strings in JavaScript are defined using " or '. The “ is not a valid character for doing that so the code results in an error.
