Building Effect From Real Startup Pain
- Michael Arnaldi built an effects system in TypeScript after facing high JVM infra costs and developer scarcity.

- TypeScript is JavaScript with a compile-time type layer that disappears at runtime and improves tooling drastically.
- Its structural typing and IDE integration make it a pragmatic target for large codebases and refactoring.
Adapting ZIO Types To TypeScript
- TypeScript's unions and intersections let you model effect environment and error channels, but structural typing forces trade-offs.
- Effect adapted ZIO concepts using unions for errors and other language-specific compromises.
