You'll start with the basics types, data structures, and control flows and progress to advanced features like blocks, mixins, metaclasses, and beyond.

As you follow along, you ll learn to: Leverage Ruby's succinct and flexible syntax to maximize your productivity Balance Ruby's functional, imperative, and object-oriented features Write self-modifying programs using dynamic programming techniques Create new fibers and threads to manage independent processes concurrently Catch and recover from execution errors with robust exception handling
