What is purify?
Purify is a library for functional programming in TypeScript. Its purpose is to allow developers to use popular patterns and abstractions that are available in most functional languages. It is also Fantasy Land
- Elegant and developer-friendly API - Purify's design decisions are made with developer experience in mind. Purify doesn't try to change how you write TypeScript, instead it provides useful tools for making your code easier to read and maintain without resolving to hacks or scary type definitions.
- Emphasis on practical code - Higher-kinded types and other type-level features would be great additions to this library, but as of right now they don't have reasonable implementations in TypeScript. Purify focuses on being a library that you can include in any TypeScript project and favors clean and readable type definitions instead of advanced type features and a curated API instead of trying to port over another language's standard library.
