Is it correct to use JavaScript Array.sort() method for shuffling?

Yes, you can use the JavaScript Array.sort() method for shuffling. Let’s see how

Example

function shuffleDisplay(arr) {
   var tmp, current;
   
   // calculating length
   var top = arr.length;

   if(top) while(--top) {
      current = Math.floor(Math.random() * (top + 1));
      tmp = arr[current];
      arr[current] = arr[top];
      arr[top] = tmp;
   }
   return arr;
}
