How to add the key of the object to the array in js

I have such objects:

robot {
  id
  skill
  currentWorkPlace
}
warehouse {
  aiStaff
  currentStatus
  boxes
}

I have to write a function that should add the id of a new worker to the aiStaff array, and write a reference to the warehouse object to the job in the currentWorkPlace. But I don't know how not to change the array in the warehouse.('registerRobot' function should not rewrite array 'aiStaff' inside 'warehouse' object) and I don't have to create a new variable

There is my code:

function registerRobot(robot, warehouse) {
  robot.currentWorkPlace = warehouse;
  robot.currentWorkPlace.aiStaff = [robot.id];
}

I dont know how to not rewrite array 'aiStaff'. Please help me Guys.

It looks like your warehouse.aiStaff is an array. In this case change your function to add the robot ID to the array:

function registerRobot(robot, warehouse) {
  robot.currentWorkPlace = warehouse;
  robot.currentWorkPlace.aiStaff.push(robot.id);
}

If I understood correctly you need to 'add' a new robot, but you are having the issue that the entire array gets overridden.

Considering warehouse.aiStaff is an array, if you want to add a new 'worker' you need to push the new item into the array.

function registerRobot(robot, warehouse) {
  robot.currentWorkPlace = warehouse;
  robot.currentWorkPlace.aiStaff.push({
    id: robot.id
  });
}
