`weight-sort` is a lightweight utility for sorting an array of objects by a numeric (or comparable) property—by default the `weight` field but configurable to any key. It works in Node.js, browsers, and PHP, offering options for custom keys, descending order, or a user‑supplied compare function, and preserves the original array’s order for equal values. The library is aimed at developers who need a simple, cross‑environment way to order collections without writing their own sort logic.
