    If you cannot use neither an explicit if statement nor a ternary operator, you can use an object as dictionary for the various cases, like:

    function compare(a, b) {
    return ({
        '-1': 'a lesser than b',
        0: 'a equals b',
        1: 'a greater than b'
    })[Math.sign(a - b)];
}

compare(4, 2) // returns 'a greater than b'
compare(3, 3) // returns 'a equals b'
compare(3, 5) // returns 'a lesser than b'

    One way to do this is by using a ternary operator, which is a concise way to write conditional statements. possible solution,

    function compareNumbers(a, b) {
  return a > b ? 'a greater than b': 'a less than b'
}

console.log(compareNumbers(4,2));

    How about this way ?

    function compare(a, b) {
    return `${Math.max(a, b)} is greater than ${Math.min(a, b)}`;
}

console.log(compare(2, 4)) // '4 is greater than 2'
