I have a Angular project and I use the Signalr inside it.
But when I get the connectionId , I can print it.
But I can't assign it in the global variable. This is my code:

```
   connection = new signalR.HubConnectionBuilder().withUrl("http://localhost:8178/notifyHub").build();
    connection.start().then(function () {
      connection.invoke("GetConnectionId").then(function (connectionId) {
       console.log(connectionId);
       // var temp=connectionId
      })
    }).catch(err => console.error(err));

```
