+According to Wikipedia, Ruby is a general-purpose language that first appeared back in 1995 in Japan. 
+Apparently, Ruby is a truly object-oriented language in the sense that almost everything is an object. 
+In fact, even numbers are objects in Ruby which means they can be subjected to the dot operator. How cool is that?
+
+Today, the other major industry languages like Python and Java are more popular general-purpose languages, 
+so Ruby often finds its place as a web development language. This is probably due to the Ruby on Rails 
+framework which helps developers build web applications quickly and easily.
