The Fundamentals of Ruby

An introduction to the basic concepts of programming with Ruby. Information, exercises and code all related to learning Ruby.

The presentations are powered by Rabbit.

The normal code samples and examples are meant to be used with Hackety Hack.

The vanila code samples and examples are meant to be used with IRB or Ruby run from the terminal.

• Data types like Strings, Numbers and Floats
• Math with numbers
• String manipulation
• Variables
• User input
• Boolean
• Loops
• Shoes

Ideas of things to try and use

• Ruby from the command line
• IRB
• Shoes
• Camping
• Sinatra

Things to Note & Teach

How to Save a File
