Can the variable name within a function be retrieved?

How can I retrieve the variable name (user_name1 or user_name2) from a sample function (GetUserName()) within itself? This variable name is required to create an object with the same name on the server side for data synchronization purposes.

function GetUserName(){
  let result_variable_name = ????; // If (1) then result_variable_name == 'user_name1', if (2) then result_variable_name == 'user_name2'
  socket.send("object_name", result_variable_name);
  return "Some user name";
}
let user_name1 = GetUserName(); //(1)
let user_name2 = GetUserName(); //(2)

Is it possible to achieve this? How can it be done?

Answer №1

A resounding no. Variable names should be devoid of any inherent meaning. They are merely temporary labels within an algorithm, often beyond your control in terms of naming conventions. Furthermore, the variable may not even exist when the function is called, making it impossible to predict what value it will hold.

Consider this:

let players = [GetPlayerName(), GetPlayerName()];

What next?

Explicitly pass the name into the function without hesitation.

GetPlayerName('player_name1')
