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.
