Can I add variable into ScriptsListener code?

Question

I Have photoshop generated script which change current layer name to NewName

Question : It is posible to change that static value to variable value

Here is Code

function Rename() {
  // Set
  function step1(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    var ref1 = new ActionReference();
    ref1.putEnumerated(cTID('Lyr '), cTID('Ordn'), cTID('Trgt'));
    desc1.putReference(cTID('null'), ref1);
    var desc2 = new ActionDescriptor();
    desc2.putString(cTID('Nm  '), "NewName");
    desc1.putObject(cTID('T   '), cTID('Lyr '), desc2);
    executeAction(cTID('setd'), desc1, dialogMode);
  };

All i want is to remove that "NewName" String and put variable defined from outside of function like

var DynamicName = prompt("Your Name","");

so instead of that NewName i want to call DynamicName Variable! is that possible? I want this cuz sometimes i need to change document name or layer name from my old stored variable from script.

Like in any other language, in javascript you can pass parameters to functions:

rename(DynamicName); //you're passing a parameter DynamicName to function rename()

function rename(newName) { //newName will be a variable name for parameter
    //babla
    desc2.putString(cTID('Nm  '), newName);
    //blabla
};

and you can send a number of variables:

rename("beautiful layer", 10);

function rename(newName, id) {
    //babla
    desc2.putString(cTID('Nm  '), newName); // your variable
    ref.putIdentifier(cTID('Lyr '), id); //second variable
    //blabla
};

or if your variable is defined outside rename() scope you can use it directly:

function rename() {
    //babla
    desc2.putString(cTID('Nm  '), DynamicName); // your variable
    //blabla
};

I'd recommend to do course on the JS on codeacademy or something similar to learn about it, it won't take more than an hour for basics like this.
