1. By Timothy Sparks

2. 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

3. 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

4. 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

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

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

7. Completely OO / Psuedo- procedural. Very Simple Object Creation

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

9. 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

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

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

12. Basic Condensed Object Oriented
