The **string-indexes** package provides a tiny utility function that scans a string and returns the starting positions of every non‑overlapping occurrence of a given substring (e.g., `getIndexes('xxxx__xxxx', 'xx')` → `[0, 2, 6, 8]`). It’s aimed at JavaScript/TypeScript developers who need a simple, zero‑dependency way to locate all substring indexes in their code.
