I just need a deep explanation about my code
Describe your issue in detail here.

  **Your code so far**

function destroyer(arr) {
var valsToRemove = Array.from(arguments).slice(1);
return arr.filter(function(val) {
  return !valsToRemove.includes(val);
});
}


destroyer([1, 2, 3, 1, 2, 3], 2, 3);

That looks more like solution 2 from the hints section than your own code. But anyway.

This line is storing an array of the elements that should be removed in a variable called valsToRemove (in your example, that’s [2,3]):

var valsToRemove = Array.from(arguments).slice(1);

The function returns the array that was passed in, with the values to remove filtered out:

return arr.filter(function(val) {
  return !valsToRemove.includes(val);
});

Since valsToRemove is an array, you can use .includes on it. The filter only lets pass items/returns true for all the items of arr that are not included in valsToRemove.
