Abstract
In Chapter 1 the Ruby programming language is introduced. Ruby is installed using the Ruby Installer for Windows. The Irb (Interactive Ruby shell) is used to run Ruby scripts. The syntax of the Ruby language is discussed. Ruby provides identifiers and comments, strings, arrays, hashes and ranges, variables, constants and operators, classes, methods, procs and blocks. Ruby also provides modules with which multiple inheritance may be added to Ruby with mixins. Ruby also provides exception handling. Ruby is similar to PHP and Java as Ruby, PHP and Java are object-oriented languages. Ruby is different from PHP and Java in some respects too.
