How to get Dynamic values using Pre-Request Script and concatenate

Hello Dears,
Hope everyone doing well.
I have the requirement to get values dynamically.
Base URL: http://localhost:8080/identityiq/rest/identities
Example :
Body :

 "firstname": "Anand",
"lastname": "Thivari" 

But here above I need to pass one more required variable is “name”. And “name” should be like “firstname”.“lastname”
Ex . Anand.Thivari
But I want the “name” variable as dynamically assign when the request is sent to the server.
Likewise, “email” also posts dynamically.
Can anyone suggest how to resolve it?
Thanks in advance.!

Thank god, I resolved myself.

Method: POST
Base URL: http://localhost:8080/identityiq/rest/identities/
Body : json-raw

    "firstname" : "{{firstname}}",
    "lastname" : "{{lastname}}",
    "name" : "{{name}}",
    "email" : "{{email}}"

Pre-request Script:

var fname = "Aravind";
var lname = "Thivari";
var fullname = fname+"."+lname;
var email = fname+"";


Thanks and pls suggest to me if have any other way.
