I am asked to process two or more arrays sent from a function. But the function only sends one argument. I do not know if the problem is wrongly formulated or if it is really possible to do so. This is what I have done so far:

function uniteUnique(arr) {
  var newArr=[];
  var args = Array.from(arr);

  for(i=0;i<arr.length;i++){
    if(Array.isArray(arr[i])){
      for(j=0;j<arr[i].length;j++){
        if(!newArr.includes(arr[i][j])){
          newArr.push(arr[i][j]);
        }
      }
    }else{
      newArr.push(arr[i]);
    }
  }
  return newArr;
}

uniteUnique([1, 3, 2], [5, 2, 1, 4], [2, 1]);

javascript

Can I modify the errors that PHP gives you? Update magento v 2.1.7 a v 2.2.2 does not recognize shipping

The only solution would be to send an array (array) of fixes, so you only receive one parameter but you can manipulate the ones you want, as long as they are inside the argument

Let's see if this helps you, all I did was add [before and] after your declaration of arrangement ... So I group all your arrangements into one ...

function uniteUnique(arr) {
  var newArr=[];
  var args = Array.from(arr);

  alert(args);

  for(i=0;i<arr.length;i++){
    if(Array.isArray(arr[i])){
      for(j=0;j<arr[i].length;j++){
        if(!newArr.includes(arr[i][j])){
          newArr.push(arr[i][j]);
        }
      }
    }else{
      newArr.push(arr[i]);
    }
  }
  return newArr;
}

$('#procesar').click(function(){
  var arr = uniteUnique([[1, 3, 2], [5, 2, 1, 4], [2, 1]]);
  $('#resultados').text(arr);
})
