Olawale/FreeCodeCamp Algorithm: Seek And Destroy

seek_and_destroy.js

 function destroyer(arr) {
   // Covert the arguments into a workable array and changeable array.
   var args = Array.prototype.slice.call(arguments);
   
   // Save the first part of the arguments which is our actual array
      var mainArr = args[0];
   
   // Remove the first part of the argument from the array which it the array in array
   // This would return the other parts alone in the array since arr.splice mutates the array unlike slice
     args.splice(0,1);
   
   // Now filter the mainArr and return only items not present in the arg array
   return mainArr.filter(function(item){return args.indexOf(item) === -1;});
   
}
destroyer([1, 2, 3, 4, 5, 6],2, 3, 4, 5);
