SpiralLoop is a tiny npm library that generates coordinates for a “spiral” traversal of a grid, starting from the center rather than a corner. By supplying an array of side lengths (and optionally a custom centre point), you get a callback invoked with each `(x, y, …)` position; returning `true` breaks the loop. It’s useful for JavaScript developers who need to iterate outward from a central cell in games, simulations, image processing, or any grid‑based algorithm.
