 When working with JavaScript, you may encounter situations where you need to repeat a string a specific number of times.

 `string` is the string that you want to repeat, and `count` is the number of times you want the string to be repeated. Here's an example:
 
+:::interactive_editor
+
 ```js
 let word = "Hello!";
 let repeatedWord = word.repeat(3);
-console.log(repeatedWord);  // Output: "Hello!Hello!Hello!"
+console.log(repeatedWord);  // "Hello!Hello!Hello!"
 ```
 
+:::
+
 In this case, the string `Hello!` is repeated three times, resulting in `Hello!Hello!Hello!`.
 
 While the `repeat()` method is useful, there are a few exceptions and limitations to keep in mind.
@@ -47,18 +51,26 @@ console.log(word.repeat(Infinity));  // Throws RangeError: Invalid count value
 
 If the count is not an integer (such as a decimal like `2.5`), the `repeat()` method will round it down to the nearest integer.
 
+:::interactive_editor
+
 ```js
 let word = "Test";
-console.log(word.repeat(2.5));  // Output: "TestTest"
+console.log(word.repeat(2.5));  // "TestTest"
 ```
 
+:::
+
 If you pass `0` as the count, the `repeat()` method will return an empty string.
 
+:::interactive_editor
+
 ```js
 let word = "Test";
-console.log(word.repeat(0));  // Output: ""
+console.log(word.repeat(0));  // ""

 The `repeat()` method can simplify tasks that involve string duplication, making your code more concise and readable.
 
 Whether you're generating repeated text patterns or filling a space with characters, `repeat()` can save you from writing loops or more complex code.
