Returns the <script> element whose script is currently being processed.

Syntax

JavaScript
var <var>curScriptElement</var> = document.currentScript;

  console.log("Executing asynchronously");
} else {

Notes

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.
