  Functional programming in TypeScript

I released fun v1.0.0 today. Over the last year or so I've been playing with higher kinded type implementations and various APIs in the style of fp-ts but built in deno. About 3 months ago I hit on what felt (to me at least) like the best API in terms of ease of understanding and use. Since then I've been paring down the API surface, simplifying implementations, and pushing test coverage to 100%. While this project started as a learning tool for me it has since become trustworthy enough to use as production code.

  Documentation generator for Deno

  

While the documentation is lacking (mostly due to the freshness of deno_doc), I've decided that the library is ready for its 1.0.0 release. I've used almost every algebraic data type in this library in production and have encountered a grand total of zero bugs resulting from this library. That said, if you find any edge cases not covered by the test suite, please reach out!
