The **array‑remove‑by‑index** package provides a tiny utility function `removeByIndex(index, array)` that deletes a single element from a JavaScript array in‑place, accepting both positive and negative indices. It’s aimed at developers who need a simple, dependency‑free way to splice out items by position without writing their own loop or using `Array.splice` directly. The library is distributed via npm and can be imported as an ES module.
