Yukihiro Matsumoto wanted “a scripting language that was more powerful than Perl, and more object- oriented than Python. That's why I decided to design my own language“ Created in 1995

Looks like the love child of Perl, C, and Ada. Implicitly declared data types (example = 5) # - Comments Built in data conversion x.to_- (similar to C# VariableName.toString) Supports regular expressions

For (Var) in [1,3] do …. end Range does not have to be single data type [1,”two”, [3,4,5.0]].each do |Var| While do, do while, until, loop statements

Case (MommySays) when (ImSpecial) : print “I like chocolate milk” else …. End If (boolean) ….. Elsif …. Else …. End

Allows for custom classes Allows for changing existing classes (method overridding)

Completely OO / Psuedo- procedural. Very Simple Object Creation

C-based Begin …. Rescue (Exception) #Catch () in C …. End Custom Exeptions

Support began in 1.8 (currently stable at 1.9.2) JRuby – allows for currency prior to 1.8 (no Global Interpreter Lock ) < 1.8: pseudo-concurrency

Ruby On Rails Completely free Compiler for Mac, Linux, Windows No need for an IDE

Readability: 9 Writeability: 9 Reliability: 9 Cost: FREE!!! (unlike food)

Basic Condensed Object Oriented
