ok sory can i delete it? i cant see that option

also, there is no question here ... (?1) this code passes the kata. there is no point in posting your solution

don't post code without the spoiler tag, I just added it to your comment

Tests show what test cases you fail:

Testing for http://www.0e82wq13dj590y790gc.fr/archive/
    expected 'www' to equal '0e82wq13dj590y790gc'  
    
Testing for asq1m3fb5zik8h-ejb-48pcpmijh.us/img/
   expected undefined to equal 'asq1m3fb5zik8h-ejb-48pcpmijh'    

Your solution returned "www" in the first case, and undefined in the second, which are not correct answers.
Your solution has a bug. Bug in your solution is not a kata issue.

Test Passed: Value == 0
Test Passed: Value == 2
