What’s Ruby?

• An 100% OO language (well, 99.9%)

• Dynamically typed language

• Concise. Simple. Fun!

• Multi-platforms

Smalltalk Perl Lisp Scheme Python CLU Eiffel Ada Dylan

Why Ruby?

Communities

Simplicity

Everything in Ruby is Object

Array

Hash

Range

Methods

Mixins

Duck Typing

If it walks like a duck, And talks like a duck,

Then we can treat it like a duck. (who cares what it really is)

– Add method to object even at Runtime!
