My goal is to define this user as an array.
users = new BehaviorSubject<any>([]);
In my component, I am attempting to add the userID to the array.
this.Service.users.push(userID);
To subscribe to it, I use the following code:
this.Service.users.subscribe(x=>{
});
However, I am encountering the error message:
The property 'push' does not exist on type 'BehaviorSubject'
The data structure of this.Service.users is not actually an Array, but rather a BehaviorSubject<any>.
To properly handle this, consider the following approach:
// create a copy of the current value
const updatedValue = this.Service.users.value.concat();
// add the new userId
updatedValue.push(userId);
// update the value
this.Service.users.next(updatedValue);
