Issue encountered while trying to set a property in ECMAScript 6

I am attempting to create a class in ecmascript 6.

Below is the code:

class Machine {
   constructor (){
      this._context = null;
   }

   get context (){
      return this._context;
   }

   set context (context){
      this._context = context;
   }   
}

However, I consistently encounter the same error for the setter in Webstorm: "Set accessor method has type that is not compatible with get accessor type"

I am puzzled as to why this error is occurring. I followed the instructions provided here:

EDIT: It appears that the issue only arises because I defined my class within an angular factory.

My question now is how can I correctly define a class within an angular factory?

Perhaps I am not supposed to do it in that manner.

EDIT 2: Here is my angular factory:

angular.module('frontEndApp')
  .factory('Machine', function () {

     class Machine {
        constructor (){
           this._context = null;
        }

        get context (){
           return this._context;
        }

        set context (context){
           this._context = context;
        }   
     }

     return Machine;
  }

Answer №1

It seems like WebStorm is having trouble determining the type of the property this._context. To assist WebStorm in resolving this issue, consider adding annotations to your code (I encountered a similar problem):

class Machine {
   constructor (){
      this._context = null;
   }

  /**
   * Proxy method for accessing context.
   *
   * @return {ContextInterface}
   */
   get context (){
      return this._context;
   }

   /**
    * Sets the appropriate context.
    *
    * @param {ContextInterface} context
    */
   set context (context){
      this._context = context;
   }   
}

Answer №2

Your ES6 (ES2015) script is accurate. It seems there may be a glitch in WebStorm related to the updated syntax (although the mention of "type" is unexpected, considering JavaScript's loose typing nature; you should verify that it isn't configured for TypeScript or equivalent).

Answer №3

Your Webstorm configuration seems to be causing the problem. Are there any linters or similar tools active? It may not be recognizing JavaScript for some reason.

The code itself appears to be correct.
