Answer 1

The following example demonstrates how to set Group as a field value via SharePoint JSOM API.

Lets assume group variable represents SP.Group object which has been retrieved from the server, then list item user field value for a SharePoint Group could be set like this:

let groupVal = new SP.FieldUserValue();
groupVal.set_lookupId(group.get_id());

listItem.set_item(userFieldName, groupVal);
listItem.update();
ctx.executeQueryAsync(() => {
     //...
}, (sender, args) => {
    //handle error
});
