A functional programming library for JavaScript that uses named-argument style methods to eliminate parameter order concerns.
FPO is a functional programming library for JavaScript that introduces a named-argument style API. It solves the problem of remembering parameter order in traditional FP libraries by allowing developers to pass arguments as object properties, which can be in any order and optionally omitted. This makes currying and function composition more intuitive and less error-prone.
JavaScript developers familiar with functional programming concepts who want a more ergonomic and flexible API, especially those working with currying, composition, and interoperability between different function parameter styles.
Developers choose FPO for its unique named-argument approach that eliminates parameter order concerns, simplifies currying, and provides seamless adaptation between named and positional argument styles, reducing boilerplate and cognitive load compared to traditional FP libraries.

Core methods use object destructuring so arguments can be in any order and optional ones omitted, removing common FP errors like misplaced parameters—evident in the reduce example where 'arr' and 'fn' are swapped.
Curried methods accept named arguments in any sequence, eliminating argument juggling; the README shows FPO's currying is straightforward compared to the complex partialRight/flip chain in traditional libraries.
FPO.apply and FPO.unapply allow easy conversion between named and positional argument styles, demonstrated with the ajax callback example for interoperability.
Provides FPO.std.* namespace with traditional positional arguments similar to Ramda, ensuring a fallback for developers accustomed to standard FP libraries.
Instead of relying on order, developers must learn specific names like 'fn', 'v', 'arr'—the README admits this trade-off and lists conventions, which can be error-prone if forgotten.
Every function call requires an object literal, making simple operations more wordy than traditional FP calls; for example, basic map or reduce calls are wrapped in objects.
The named-argument approach is unique and may not integrate smoothly with the broader JavaScript FP ecosystem, potentially limiting community support and tooling.
