Explanation:

Step1: Check if actor exists

Use if (actorName in cast) to check if the actor is in the cast object.

Step2: Delete actor if exists

If exists, use delete cast[actorName] to remove the actor from the cast object and return "Actor deleted".

Step3: Return message if not exists

If not exists, return "Not in this cast".

    if (actorName in cast) {
        delete cast[actorName];
        return "Actor deleted";
    }
    return "Not in this cast";
}
