  <script> 
  var func = function(x,indx,str){ 
    return indx == 0 ? str : func(x,--indx,(str +=" " + x[indx]));; 
    } 
  var arr = new Array("apple","banna","orange","apple2","apple3"); 
  var arr1 = arr.slice(0) 
  var arr3 = func(arr1,arr1.length,""); 
  var arr2 = arr.slice(0).reverse(); 
  console.log(arr2); 
  console.log(arr); 
  console.log(arr3);
