 There are two powerful methods in JavaScript for handling JSON data: `JSON.parse()` and `JSON.stringify()`. These methods are commonly used to convert between JSON strings and JavaScript objects.

 The `JSON.stringify()` method also accepts an optional parameter called a replacer, which can be a function or an array. Here is an example of using an array for the optional replacer parameter:

 In this example, we have a `developerObj` with four properties. When we use the `JSON.stringify()` method, we can pass in an array for the second parameter and specify which properties we want stringified. The result will be a stringified object containing only the `firstName` and `country` properties. 
 
 Another optional parameter for the `JSON.stringify()` method would be the spacer parameter. This allows you to control the spacing for the stringified result:

 Most of the time you will not be using either of these optional parameters for the `JSON.stringify()` method but it is still helpful to be aware of them. 
 
 Another method you will be using a lot in your programming is the `JSON.parse()` method. `JSON.parse()` converts a JSON string back into a JavaScript object. This is useful when you retrieve JSON data from a web server or from `localStorage` and you need to manipulate the data in your application. You will learn more about `localStorage` in a future lesson. 
 
 Here's an example on how to work with the `JSON.parse()` method:
 
+:::interactive_editor
+
 ```js
 const jsonString = '{"name":"John","age":30,"isAdmin":true}';
 const userObject = JSON.parse(jsonString);
+console.log(userObject);
+
+// Result:
+// { name: 'John', age: 30, isAdmin: true }
 ```
 
-The JSON string is parsed back into a JavaScript object that looks like this:
-
-```js
-{
-  name: "John",
-  age: 30,
-  isAdmin: true
-}

+:::
 
 This allows you to work with the data in your program as a normal JavaScript object, making it easier to manipulate and use.
