# Welcome
Funkcia is a TypeScript library that provides robust error handling and functional programming primitives, heavily inspired by Rust's error handling patterns and functional programming concepts.
It provides a comprehensive toolkit for writing more reliable code with better error handling and functional programming patterns, making it easier to write maintainable and type-safe applications.

### Docs parity checklist
Before publishing docs updates:
* Verify public API names against source exports in `/packages/funkcia/src`.
* Ensure method headings match API casing exactly.
* Remove stale methods that no longer exist in source.
* Confirm `SUMMARY.md` links point to real files.
* Run a quick search for known removed APIs to avoid drift regressions.
