 Taking our hiring manager example above. First of all we have an interviewer interface and some implementations for it
 
-```php
-interface Interviewer {
- public function askQuestions();
-}
+```js
+/*
+Interviewer interface
 
-class Developer implements Interviewer {
- public function askQuestions() {
- echo 'Asking about design patterns!';
- }
+askQuestions()
+*/
+
+class Developer {
+ askQuestions() {
+ console.log('Asking about design patterns!')
+ }
 }
 
-class CommunityExecutive implements Interviewer {
-  public function askQuestions() {
-  echo 'Asking about community building';
-  }
+class CommunityExecutive {
+ askQuestions() {
+ console.log('Asking about community building')
+ }
 }
 ```
 
 Now let us create our `HiringManager`
 
-```php
-abstract class HiringManager {
- 
- // Factory method
- abstract public function makeInterviewer() : Interviewer;
- 
- public function takeInterview() {
- $interviewer = $this->makeInterviewer();
- $interviewer->askQuestions();
+```js
+class HiringManager {
+ 
+ takeInterview() {
+ const interviewer = this.makeInterviewer()
+ interviewer.askQuestions()
  }
 }
 ```
 Now any child can extend it and provide the required interviewer
-```php
+```js
 class DevelopmentManager extends HiringManager {
- public function makeInterviewer() : Interviewer {
+ makeInterviewer() {
  return new Developer();
  }
 }
 
 class MarketingManager extends HiringManager {
- public function makeInterviewer() : Interviewer {
+ makeInterviewer() {
  return new CommunityExecutive();
  }
 }
 ```
 and then it can be used as
 
-```php
-$devManager = new DevelopmentManager();
-$devManager->takeInterview(); // Output: Asking about design patterns
+```js
+const devManager = new DevelopmentManager()
+devManager.takeInterview() // Output: Asking about design patterns
 
-$marketingManager = new MarketingManager();
-$marketingManager->takeInterview(); // Output: Asking about community building.
+const marketingManager = new MarketingManager()
+marketingManager.takeInterview() // Output: Asking about community buildng.
 ```
