**ad‑utils** is a JavaScript utility library published by RED Interactive Agency’s ad‑tech team. It bundles a collection of stand‑alone helper functions for common tasks (array manipulation, math & geometry, color conversion, object handling, text processing, image fitting, motion control, GPS lookup, and video metrics) that are useful when building advertising or interactive media web projects. The package is aimed at front‑end developers working on ad‑tech creative code who need a lightweight, reusable toolkit.
