Tell us what’s happening:

  **Your code so far**


function sym(...args) {
let temp = [];
for (var arg of args[0]) {
  if(args[1].includes(arg)){
    while(args[1].includes(arg))
      args[1].splice(args[1].indexOf(arg),1);
    continue;
  }
  else {
    if(!temp.includes(arg))
      temp.push(arg);
  }
}
for (var arg of args[1]) {
  if(!temp.includes(arg))
      temp.push(arg);
}

args.splice(0,2);
args.unshift(temp);
if (args.length > 1) {
  sym(...args)
}

if (args.length == 1) {
  temp.sort(function (a, b) {
    return a - b;
  });
  console.log(temp)
  return temp;
}
}

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

Consider whether it’s possible that what function prints to console is not actually what it’s returning in the end.
