The **country‑telephone‑data** package provides a ready‑made list of world‑wide telephone information—each entry includes the country name, ISO‑2 code, international dialing code, a sample number format, and whether the country uses area codes. It exports the data both as an array (`allCountries`) and as a quick‑lookup object keyed by ISO‑2 (`iso2Lookup`), making it useful for developers who need to validate, format, or display phone numbers in web or Node.js applications.
