QuestionHow does the compare function work with numerical sort? Pin

I'm taking the w3schools tutorial on javascript. In the tutorial it is discussing numerical sort. It says since javascript doesn't sort numerals you need to use a trick of employing a comparison function with sort.

JavaScript
<pre><!DOCTYPE html>
<html>
<body>

<h2>JavaScript Array Sort</h2>
<p>Click the button to sort the array in ascending order.</p>

<button onclick="myFunction()">Try it</button>
<p id="demo"></p>

<script>
const points = [40, 100, 1, 5, 25, 10];
document.getElementById("demo").innerHTML = points;  

function myFunction() {
  points.sort(function(a, b){return a - b});
  document.getElementById("demo").innerHTML = points;
}
</script>

</body>
</html>


How does function(a, b) get the input a and b? If you could give a detailed message because I'm not getting how it all works.
