Ruby Programming Eğitimi

Ruby is a fully object oriented, dynamically typed scripting language. It has matured and expanded rapidly since its power was showcased by the ‘Ruby on Rails’ web framework. Today it is both the de facto replacement for the Perl scripting language and an increasingly important part of the Java and .NET platforms (via the JRuby and IronRuby interpreters).

This course provides experienced developers with everything they need to start using Ruby in production applications. The complete syntax of the language is covered, including detailed discussion of patterns, idioms and programming styles. Following this the course explores standard libraries and tools, and concludes with in-depth coverage of the JRuby interpreter and Java/Ruby integration.
