Article part:
================
string = " this is a string " 

You can apply the strip! method to it, like this: 

   string.strip!  ==>  "this is a string"


  Methods which have a "!" at the end are destructive; they change the
object they are applied to. 

 Now, let's capitalize our string: 

   string.capitalize!  ==>  "This is a string"
===================

Actually, expressions like string.capitalize! are
evaluated to nil:

string.capitalize!  ==>  nil

If it were

       string.capitalize

then we could add 

      ==>  "This is a string"

A bit confusing ...


Just my two roubles.
