JavaScript method to implement random sorting of arrays_javascript skills

The example in this article describes how to implement random sorting of arrays in JavaScript. Share it with everyone for your reference. The specific implementation method is as follows:

function Shuffle(o) {
  for(var j, x, i = o.length; i; j = parseInt(Math.random() * i), x = o[--i], o[i] = o[j], o[j] = x);
  return o;
};

How to use:

var testArray = [1,2,3,4,5];
Shuffle(testArray);
// jQuery to dump out new values to element with ID of 'dump'
$(function() {
  for (var i=0;i<testArray.length;i++) {
   $("#dump").append(testArray[i]);
  }
});

Output result:
