Work around without using javascript object in this case -

I was used to programming using python but I am using javascript for some project . In Python, the concept of OOP was a bit easier than Javascript which I'm just reading. That being said, I'm not very comfortable using the javascript object and prototype right now. In the meantime, can I get the following without using the object? I'm not a pure programmer (always taken as a hobby), so please bear with me:

  function func1 (arg1) {item does. .1 .. For example ... var result = ARG1 * 2; Item does .2 for example ... var resultSq = arg * arg; ......}   
 I want another function, say func2 which when calls func1; Funct1 only responds by displaying items ... 1 and returning results.  
 In other words, I want to know who called the function and if sorry for changing the statement execution, it is very easy. / P>  
 
 
 Where is the caller:  
    
 Reference:  
 Passing an ID:  
 As the caller really depends on how the interrogator actually acts differently If you have a statement, it checks to see what action should be taken.  
  function doSomething (action number) {if (actionNumber == 1) {return 1; } And if (action number == 2) {return1; } // etc ...} function2 () {doSomething (1); }
