Comprehensive Ruby Programming

Ruby Methods

One of the most powerful tools available to developers is the ability to store functionality and share that behavior throughout a program. In this chapter, you'll learn how to create and use methods in Ruby programs to store processes and reuse them throughout a program, including an overview of procs and lambdas. Additionally, we'll walk through how you can do the following:

• Demonstrate how to build methods in Ruby to encapsulate various processes
• Develop proc- and lambda-based programs and show when to use closures instead of traditional methods
• Recommend how to work with the full list of method argument options, including traditional, splat, named, and default arguments
