The **load‑script** package provides a tiny utility for dynamically injecting a `<script>` tag into a web page so that a JavaScript file is fetched and executed asynchronously. It works in Node‑style environments (via `require('@segment/load-script')`) and accepts either a simple URL string or an options object that selects a URL based on the current page’s protocol, invoking an optional callback when the load succeeds or fails. The library is aimed at front‑end developers who need a reliable, minimal way to load third‑party scripts (e.g., analytics) on the fly.
