A functional programming utility library for immutable and pure date manipulation in JavaScript.
date-fp is a functional programming utility library for manipulating dates in JavaScript. It provides pure, autocurried functions that treat dates immutably, solving the problem of integrating date operations into functional programming contexts where object-oriented libraries are awkward to use.
JavaScript developers working in functional programming paradigms, especially those using libraries like Ramda, who need immutable and composable date manipulation utilities.
Developers choose date-fp for its strict adherence to functional principles—pure functions, autocurrying, and immutability—making it ideal for predictable and composable date handling in functional codebases.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
All functions are side-effect free and never mutate date objects, ensuring predictable behavior as emphasized in the README for robust date handling.
Functions are automatically curried, allowing easy partial application and seamless composition in functional workflows, as stated in the key features.
Designed to work smoothly with functional libraries like Ramda, making it ideal for integrating date operations into functional programming contexts.
Built on principles of purity and immutability, it reduces common bugs related to date mutations in complex applications, as highlighted in the motivation.
Its strict adherence to functional programming can be a barrier for developers used to object-oriented paradigms, requiring additional learning and adjustment.
Compared to comprehensive libraries like Moment.js, date-fp lacks built-in support for complex formatting, timezones, or localization, focusing on core functional operations.
As a specialized library, it has fewer contributors and plugins, which could limit community support and extensions compared to mainstream date libraries.
