or iterating over arrays, etc.
The beauty of ruby is apparent, rails or not. But if you are doing a web
application with rails, you always have the full functionality of ruby.
Whenever something doesn't already exist for rails, you can add ruby
gems and if there isn't a ruby gem, you just write your code.
Then of course, you can simply open an irb and test out a section of
code without having to deal with a web browser, apache etc.
I find myself manipulating data in a db using the irb console rather
than phpmyadmin or mysql shell because it is so much easier to
loop/iterate/replace/save.
