using regular expressions in javascript : I am trying to manipulate the string as following 
myStr = 'str1/str2/str3a // str3b'. I would like to get the last value seperated by delimiter '%s/%s', in this case 'str3a // str3b'. I tried using string split, but it splits based on '//' and returns str3b. Is there a way i can address this problem using regex?

Thanks
