Hi how should i iterate array of variables and reassign value to each variable. E.g in jQuery

function test(param1, param2) {

  $.each([param1, param2], function (i, v) {
     //check if all the input params have value, else assign the default value to it
     if (!v) 
         v = default_value; //this is wrong, can't use v, which is value
  }

}

How should I get the variable and assign new value in the loop?

Thank you very much!
