You’ll learn the fundamentals of procedural and object oriented Ruby and reinforce your learning throughout by cumulatively building a Tic Tac Toe command line application game. In this way you’ll learn how to think like a programmer and structurally break down complicated problems into smaller component. Below is a general overview of what's covered. You'll notice that many of the concepts below will look familiar to you as you've already covered them in the Javascript units.

• Debug Ruby Programs using IRB
• Explain how to debug code by running tests and solving error messages
• Identify four common types of error messages

• Create and declare variables
• List and create the six data types in Ruby
• Create and manipulate arrays

• Create methods that take in single, multiple, and no arguments
• Return values from methods
• Read and describe the various parts of error messages in tests

• Define command line applications as programs that interact directly with the computer’s shell and terminal
• Describe the file structure of a CLI
• Capture user input in a CLI
• Build a simple CLI

• Use conditional statements and comparison operators to control the flow of a program

• Use looping to tell a program to perform a repetitive action
• Build methods using while and until loops
• Distinguish between looping and iteration
• Iterate over arrays using boolean enumerators (#all?, #none?, #any?, #include?)
• Iterate over arrays using search enumerators (#select, #detect, #reject)
• Create and iterate over nested arrays

• Describe Ruby classes and create instances of a class
• Call and build instance methods on an object
• Distinguish between instance and local variables
• Explain how instance variables give objects attributes and properties
• Define methods that read and write to instance variables
• Create object properties using methods and instance variables
• Build and use setter and getter methods
• Instantiate instances of classes
