Vertex Flow is a course that helps you move from using Ruby's built-in tools to understanding how to create your own abstractions and organize large codebases. 🌊After Pulse Forge, you are already comfortable with blocks, iterators, and collections. Now it's time to explore how Ruby lets you modify the language itself to fit your needs: modules, mixins, basic metaprogramming, and combining them without creating chaos. What’s included7 modules with videos, in-depth examples, in-code comments, exercises on creating custom modules, and refactoring real scenarios.Module 1: Modules as composition toolmodule vs class • include vs extend vs prepend • Module.nesting and Module.constantsModule 2: Mixins in actionCreating functional modules • Concerns pattern (like in Rails, but without Rails) • name conflicts and superModule 3: Singleton methods and metaclassdef self.included(base) • class
