Use Multiple Conditional (Ternary) Operators

I actually find if then statements much easier to read than these ones, but these seem more efficient. 

Demo

CSS

* {
  box-sizing: border-box;
  transition: all 0.2s;
  scroll-behavior: smooth;
}

JS


// this will check if a number is positive negative or zero and return that text
function checkSign(num) {
  return (num === 0) ? "zero" : (num > 0) ? "positive" : "negative";
}

var checksign_result = checkSign(10);
console.log(checksign_result);

// this is a common function just to write the content into the result div
function write_result(result) {
  var result_html = document.getElementById("result");
  result_html.innerHTML = result;
}


HTML

<div id='result' class='mb-3 alert alert-primary'>..</div>
<button onclick="write_result(checkSign(10));" class='btn btn-primary mb-1'>Run checkSign 10</button>
<button onclick="write_result(checkSign(-5));" class='btn btn-primary mb-1'>Run checkSign -5</button>
<button onclick="write_result(checkSign(0));" class='btn btn-primary mb-1'>Run checkSign 0</button>
