How to shuffle an array using javascript

How to shuffle an array using javascript

Shuffling an array means we want to randomly rearranging the list or an array.

Using algorithms we use shuffle an array.

Algorithm:

Array =[11,12,13,14,15,16]
  <button onclick="display()">
        click
    </button>
     
    <script>
 
        // Function for array shuffling
        function ArrayShuffle(array) {
            for (var i = array.length - 1; i > 0; i--) {
 
                //random number generate
                var j = Math.floor(Math.random() * (i + 1));
 
                var tempVar = array[i];
                array[i] = array[j];
                array[j] = tempVar;
            }
 
            return array;
        }
 
        //Showing result by this function
        function display() {
            var ary = [11,12,13,14,15,16]
            var ary1 = ArrayShuffle(ary)
 
            document.write("After shuffling Array: ", ary1)
        }
    </script>

 
 
     
   

Output

Before Shuffling
Array =[11,12,13,14,15,16]

After shuffling
After shuffling Array: 11,13,15,14,12,16

Algorithm:

This algorithms uses function that returns(random-0.5) as comparator to sort function.

 
Array =[11,12,13,14,15,16]
       <button onclick="display()">
        click
    </button>
  
  

Output

Before Shuffling
Array =[11,12,13,14,15,16]

After shuffling
After shuffling Array: 12,15,16,11,13,14
