Sharepoint - Java Script - Get value from people picker column in a list

Question

I have a People Picker column in my SharePoint List.

I need to get all the values (names) from this column. I am using Java script code to get the data from SharePoint lists.

My code is as below:

Here “User” is the name of the column in the list.

var enumerator = listItem.getEnumerator();
while (enumerator.moveNext()) {

var _User = "";
if (colListItem.get_item(User) !== 'undefined' && colListItem.get_item(User) !== null) {
  //Check if people picker contains more than one value
                if (colListItem.get_item(User).length > 0) {
//Check if people picker contains only one value
                if (colListItem.get_item(User).length == 1) {
                    _User = colListItem.get_item(User)[0].$2e_1;
                }
//Check if people picker contains more than one value
                if (colListItem.get_item(User).length > 1) {
                for (var i = 0; i < colListItem.get_item(User).length; i++)
  {
  //Append all User names with a semi colon separator

               _User = _User + colListItem.get_item(User)[i].get_lookupValue() + ";";
                }
                        _User.trim;
                }
                }
            }
}
}

I know I need to use the get_lookupValue for this. But If there is a single value in the people picker column, I am getting it as colListItem.get_item(User)[0].$2e_1; I figured out that I need to use $2e_1, using developer tools. Is this the right way? Is there any other better way? Please suggest some articles , informative links on this as I am very new to sharepoint and also client side object model. Thanks in advance.

A clear solution is explained here-

My way of getting value _User = colListItem.get_item(User)[0].$2e_1; is wrong.

Users can be retrieved using get_lookupvalue.

Hope this helps all those who are new to sharepoint and facing similar issue.

Thanks!
