Episode notes
Sorbet As A Productivity Tool
- Sorbet runs in the background to flag type errors and power editor features like autocompletion and go-to-definition.
- Leaning into the type system improves code navigation and design across a large codebase.
Annotate Ambiguous Parameters
- Annotate ambiguous parameters (e.g., IDs vs objects) to get type checks and method suggestions.
- Use types to quickly discover available methods and avoid mismatched operations at runtime.
Metaprogramming Versus Maintainability
- Ruby's heavy metaprogramming creates hidden definitions that challenge static typing and tooling.
- Adding a type checker can improve maintainability by discouraging overly dynamic patterns in large teams.
