How to update data from server by condition?

Question

JavaScript

Good afternoon, there is a server that can respond with a delay of several minutes.
I need that when a new element is added (POST), a GET request to the server is made and, according to the condition of receiving this new GET element, the request stops
. Not the only user will work with the server, so you can’t work with a long array!
