Use Multiple Conditional (Ternary) Operators
I actually find if then statements much easier to read than these ones, but these seem more efficient.
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>

"Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything. 'Are you feeling all right?' I asked her. 'I feel all sleepy,' she said. In an hour, she was unconscious. In twelve hours she was dead. The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was...in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunised against measles. ...I dedicated two of my books to Olivia, the first was ‘James and the Giant Peach’. That was when she was still alive. The second was ‘The BFG’, dedicated to her memory after she had died from measles. You will see her name at the beginning of each of these books. And I know how happy she would be if only she could know that her death had helped to save a good deal of illness and death among other children."
I just checked google books for BFG, and the dedication is there.
