Array Reducing Utilities

The `arrayreduce` package, currently at version 2.1.0, provides a small collection of pre-built, reusable reducer functions designed to simplify common array reduction patterns when used with JavaScript's native `Array.prototype.reduce` method. These utilities include functions for tasks such as concatenating nested arrays, performing logical AND/OR operations across array elements, and transforming an array of objects into an indexed object based on a specified attribute. Due to its last update approximately five years ago, the package is considered abandoned, lacks active maintenance, and does not provide native ES module (ESM) support or TypeScript type definitions. It targets older Node.js environments (>=4.0.0), making it less ideal for contemporary JavaScript projects without appropriate transpilation or CJS-to-ESM bridging solutions.
