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

<html>
<head>
<script>
 function quickSort(input) {
  if (input.length <= 1) return input;
  var pivot = Math.floor(Math.random()*input.length)
  var less = [], greater=[];
  var pivotElem = input.splice(pivot,1)
  for (x in input) {
   if (input[x] <= pivotElem[0])
    less.push(input[x])
   else
    greater.push(input[x])
  }
  return [].concat(quickSort(less),pivotElem,quickSort(greater));
 }
 input = []
 inputSize = 1000
  highestInputValue = 100
 for (i=0;i<inputSize;i++) {
  input.push(Math.floor(Math.random()*highestInputValue))
 }
 document.writeln(quickSort(input))
</script>
</head>
</body>
</html>

I hope this article will be helpful to everyone’s JavaScript programming design.
