This array method will helps you.

var x = 20;
var y = 89;
var z = 61;

var arr = [];

arr.push(x);
arr.push(y);
arr.push(z);

console.log(arr.sort((a, b) => a - b));

This is only correct for same digit numbers. Try it out with 1, 10 and 2. The default `.sort()` is alphanumeric/alphabetical. – Lain Jun 26 '20 at 05:37

Just by using sort() you can do this easily.

function sort() {

  var sorting = []
  
  var x = parseInt(document.getElementById("num1").value);
  var y = parseInt(document.getElementById("num2").value);
  var z = parseInt(document.getElementById("num3").value);

  sorting.push(x, y, z)
  sorting.sort(function(a, b) {
   return a - b;
  });

  console.log(sorting)
}

<input type="text" id="num1" name="" required>
<input type="text" id="num2" name="" required>
<input type="text" id="num3" name="" required>

<button type="submit" onclick="sort()">Sort</button>

@Lain Agree with you. MDN states this: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort – Always Helping Jun 26 '20 at 05:41
