fp-filters (JavaScript / TypeScript) – Curated ready-to-use functional array filter functions

Summary: fp-filters is a collection of over 130 functional programming style array filter functions for JavaScript and TypeScript. It provides reusable, composable predicates that simplify filtering logic and improve code readability by eliminating repetitive filter implementations.

What it does

fp-filters offers a curated set of high-order predicate functions designed for filtering arrays in JS/TS environments (TS/ESM/CJS). These functions cover common filtering needs such as booleans, dates, numbers, strings, objects, and positions, enabling concise and semantic array filtering.

Who it's for

It is intended for developers who frequently write array filter logic and want to reuse tested, composable predicates to reduce boilerplate and improve maintainability.

Why it matters

fp-filters eliminates the need to rewrite common filter functions repeatedly, enhancing code clarity and reducing errors in array filtering operations.
