Hello, I would know in my code how can I get the name of the user who edited the post. I can get ID from the User that modified the post, but I want to get the name.

<!-- Remote Objects definition to set accessible sObjects and fields -->
    <apex:remoteObjects >
        <apex:remoteObjectModel name="Post__c" jsShorthand="Post" fields="Name,Id,LastModifiedDate, LastModifiedById">
            <apex:remoteObjectField name="Body__c" jsShorthand="Body"/>
            <apex:remoteObjectField name="Tags__c" jsShorthand="Tags"/>
        </apex:remoteObjectModel>
    </apex:remoteObjects>

<div id="rows"> </div>

<script>
           // Create a new Remote Object
            var pt = new SObjectModel.Post();

            // Use the Remote Object to query for 3 post records
            pt.retrieve({ limit: 3 }, function(err, records){
                if(err) alert(err.message);
                else {
                             var rows = document.getElementById("rows");
                             var ptLastModifiedById  = record.get("LastModifiedById");
                             //div data
                             var postData = document.createElement('div');
                             postData.className = "postData";
                             postData.innerHTML += ptLastModifiedDate + " by " + ptLastModifiedById;
                             div.appendChild(postData);

                             rows.appendChild(div);
                       });
                  }
            });
</script>
