It is basically a function that returns
document.currentScript but with support for IE9-11, thanks to https://github.com/amiller-gh/currentScript-polyfill.
It also works around a Firefox issue when the script is called in a microtask, which makes
document.currentScript unusable in a webpack dynamic-imported chunk.
It is shipped as a utility function rather than a polyfill, because we can't easily tell if the
document.currentScript is returning
null due to the Firefox issue or because it's running in an event handler / a callback.
The implementation here may not adhere strictly to
document.currentScript spec when called in async code or in a callback. In these situations the spec calls for
document.currentScript to return
null. However, for the grand majority of your
document.currentScript needs, this utility will do the job!

const getCurrentScript = require('@soda/get-current-script') const script = getCurrentScript() // the current executing <script> element
