      Javascript consoles throw errors if Bootstrap's js file is mentioned before jQuery. Using this function such errors
      can be avoided. Used internally.
  
      Positional arguments:
      var -- value sent by list.sorted(), which is a value in Statics().all_variables.
  
      Returns:
      Either a number if sorting is enforced for the value in `var`, or returns `var` itself.
