Set Planned_For iteration to specific value in a given SATE ID

How can my code be improved? I want to update the planned for to "Recycle Bin" Iteration value based on state id.


dojo.provide("ibm.custom.script.IterationByStatus");
     dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");

     (function() {
         var WorkItemAttributes= com.ibm.team.workitem.api.common.WorkItemAttributes;
         dojo.declare("ibm.custom.script.IterationByStatus", null, {

             getValue: function(attribute, workItem, configuration) {
             
                             
               var state= workItem.getValue(WorkItemAttributes.STATE);
        console.log(typeof(state))
                    
 if (state === "com.ibm.team.workitem.taskWorkflow.state.s4") Or
(state === "com.ibm.team.workitem.retrospectiveWorkflow.state.s1") Or
(state == "com.ibm.team.apt.storyWorkflow.state.s4")                                 
                 {   workItem.setValue(WorkItemAttributes.PLANNED_FOR, "Recycle Bin");   }
                return               
             }
         });
     })();
