--description--

In the previous challenge, you used a single conditional operator. You can also chain them together to check for multiple conditions.

The following function uses if, else if, and else statements to check multiple conditions:

function findGreaterOrEqual(a, b) {
  if (a === b) {
    return "a and b are equal";
  }
  else if (a > b) {
    return "a is greater";
  }
  else {
    return "b is greater";
  }
}

The above function can be re-written using multiple conditional operators:

function findGreaterOrEqual(a, b) {
  return (a === b) ? "a and b are equal" 
    : (a > b) ? "a is greater" 
    : "b is greater";
}

It is considered best practice to format multiple conditional operators such that each condition is on a separate line, as shown above. Using multiple conditional operators without proper indentation may make your code hard to read. For example:

function findGreaterOrEqual(a, b) {
  return (a === b) ? "a and b are equal" : (a > b) ? "a is greater" : "b is greater";
}

--instructions--

In the checkSign function, use multiple conditional operators - following the recommended format used in findGreaterOrEqual - to check if a number is positive, negative or zero. The function should return positive, negative or zero.

--hints--

checkSign should use multiple conditional operators

assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?\s*?\?\s*?.+?\s*?:\s*?.+?/gi.test(__helpers.removeJSComments(code)));

checkSign(10) should return the string positive. Note that capitalization matters

assert(checkSign(10) === 'positive');

checkSign(-12) should return the string negative. Note that capitalization matters

assert(checkSign(-12) === 'negative');

checkSign(0) should return the string zero. Note that capitalization matters

assert(checkSign(0) === 'zero');
