Seek and Destroy // some problem with my code

Tell us what’s happening:
Hi everyone,

I guess this code is not the best option, but I was wandering if it’s possible to solve this problem via using this method. It is not working for some reason and I want to know why - if possible, please explain this to me (if it’s workable at all).

Thanks in advance!

Your code so far

function destroyer(arr) {
  // Remove all the values
   
  for (var i = 0; i < arr.length;i++){
    var firstElement = arr[0];
    for(var j =1; j < arr.length;j++){
    var otherElements = arr[j][0];  
    }
    for(var k = 0; k < firstElement.length;k++){
     var newArr = [];
      if (firstElement[k]!==otherElements){
        newArr.push(firstElement);
      }
      
    }
  }  
  return newArr;
}


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