Use Multiple Conditional (Ternary) Operators


Solutions

Solution 1 (Click to Show/Hide)

We need to use multiple conditional operators in the checkSign function to check if a number is positive, negative or zero.

Here’s a solution:

In the function body we need to add multiple conditional operators - as in our lesson:

{
  return num > 0 ? "positive" : num < 0 ? "negative" : "zero";
}

In this way, function can check if a number is positive, negative or zero.

Here’s a full solution:

function checkSign(num) {
  return num > 0 ? "positive" : num < 0 ? "negative" : "zero";
}
checkSign(10);
