Retrieve LMS User Name as Variable

Can I revisit this topic again? Using Phil's JavaScript I can get the student's full name from the LMS no problem. But I'd like to just get the first name to put a little personalization into the training, e.g. "Hi Erika, welcome to today's session...". How would I need to modify the script to pull just the first name?

Here is the full name script:

var player = GetPlayer();

var myName = lmsAPI.GetStudentName();

var array = myName.split(',');

var newName = array[1] + ' ' + array[0];

player.SetVar("newName", newName);

//myName = player.GetVar('myName');

//player.SetVar("newName", newName);

Thanks as always.
