When should I avoid using functional programming?

You should avoid FP when it makes code harder for your team to read, in performance-critical hot paths where intermediate allocations matter, or for very simple logic where native language features suffice.

How does this improve error handling?

It replaces hidden failure modes like try-catch blocks and null returns with the Either type, which makes potential errors explicit in the function signature and type system.

Does this skill require knowledge of category theory?

No, it is specifically designed to be jargon-free and accessible to developers without an academic background in functional programming theory.

Is this skill compatible with fp-ts?

Yes, it provides specific examples and implementation patterns optimized for the fp-ts library in TypeScript environments.

What is the 80/20 approach to functional programming?

It focuses on the 20% of FP patterns—like Pipe, Option, and Either—that provide 80% of the benefits in code reliability and readability without requiring deep mathematical knowledge.

Implements practical, jargon-free functional programming patterns in TypeScript to improve code readability and reliability.

This skill provides a pragmatic, 80/20 approach to functional programming for TypeScript developers, focusing on high-impact patterns like Pipe, Option, and Either without the academic overhead of category theory. It helps Claude guide users through the adoption of fp-ts best practices, offering clear 'when to use' and 'when to skip' advice to ensure code remains maintainable and team-friendly. By prioritizing readability over dogmatic adherence, this skill enables developers to build more robust error handling and data transformation pipelines while avoiding common pitfalls of over-engineering.
