|aren't Strings just Arrays? I have looked into the functions of the
|class and among them is self[nth] etc.. The same is there for Arrays

No.  Of course, String and Array share many method as sequences.  But
they are not identical.  String is a two face class.  A sequence of
characters, and a sequence of lines. Some like [] etc. works on
characters.  OTOH, each, sort, etc. works on lines.

Then, what do you think each_index should work on?
Characters?  Lines?

Either case, somebody suppose the other one, and get confused.
I think each_index for String is merely a source of confusion.
This is the reason why there's no each_index in String.

Did I explain properly?
