Complex filter between 2 objects and a boolean

I have this array burgerActions :

[
  {
    statusId: 2,
    label: 'Accept'
  },
  {
    statusId: 3,
    label: 'Reject'
  },
  {
    label: 'Consult'
  },
  {
    label: 'Transfer'
  }
]

and this object status which can be either :

{
  "label": "Accept",
  "id": 2
}

or :

{
  "label": "Reject",
  "id": 3
}

In a first case you have to create a new array from burgerActions array where the statusId is not equivalent to the id of the status object that we have (we can only have one status object of the 2 cases that I listed). For that I used the filter method :

const result =  burgerActions.filter((element) => {
  return element.statusId !== recommendation.status.id
})

In the second case I need a complex conditioning adding with boolean

const statusRef = recommendation.recipient

In a first case I want if statusRef is false filter the last object in the burgerAction ({label: 'Transfer'}) but not in the case if statusRef is true. I need a method that does this type of filter without using the if () conditions because there are several cases to handle.

If you want to filter the objects that doesn't have the same statusId as in the recommendation.status.id and if recommendation.recipient === true filter the ones that doesn't have statusId, you can use this condition in the filter callback function:

element.statusId !== recommendation.status.id && recommendation.recipient ? element.statusId != null : true;

Where && recommendation.recipient ? element.statusId != null : true means that if recommendation.recipient is true filter elements with a statusId.

Here's how should be your code:

var recommendation = {
  status: {
    "label": "Pending",
    "id": 1
  },
  recipient: true
};

const result = burgerActions.filter((element) => {
  return element.statusId !== recommendation.status.id && recommendation.recipient ? element.statusId != null : true;
});

Demo:

var burgerActions = [{
    statusId: 2,
    label: 'Accept'
  },
  {
    statusId: 3,
    label: 'Reject'
  },
  {
    label: 'Consult'
  },
  {
    statusId: 1,
    label: 'Transfer'
  }
];

var recommendation = {
  status: {
    "label": "Pending",
    "id": 1
  },
  recipient: true
};

const result = burgerActions.filter((element) => {
  return element.statusId !== recommendation.status.id && recommendation.recipient ? element.statusId != null : true;
});


console.log(result);
