This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Document.currentScript property returns the <script> element whose script is currently being processed and isn't a JavaScript module. (For modules use import.meta instead.)
It's important to note that this will not reference the <script> element if the code in the script is being called as a callback or event handler; it will only reference the element while it's initially being processed.
A HTMLScriptElement or null.
This example checks to see if the script is being executed asynchronously:
if (document.currentScript.async) {
console.log("Executing asynchronously");
} else {
console.log("Executing synchronously");
}
