Ampersand.js Each Utility

amp-each is a lightweight JavaScript utility module, part of the ampersand.js project, designed to provide an iteration function similar to `Array.prototype.forEach` or `_.each` from Lodash. It allows iterating over both arrays and objects, applying a callback function to each element or property. The ampersand.js ecosystem, from which amp-each originates, was popular around 2015-2017 as a modular alternative to larger frameworks like Backbone.js, favoring CommonJS modules for client-side applications. However, the project appears to be largely unmaintained, with its core modules having last seen significant updates many years ago (e.g., ampersand-state last published 8 years ago from October 2017). This package, at version 1.0.1, should be considered abandoned, lacking recent updates, active development, or a clear release cadence. Its primary differentiator was being part of a "non-frameworky" collection of modules, offering granular control over application structure.
