現在のスクリプトをロードしたスクリプト要素を見つけるにはどうすればよいですか?

var me = document.currentScript;

<script>

var me = document.getElementById('myScript');

<script data-name="myScript"></script>

var me = document.querySelector('script[data-name="myScript"]');

<script src="//example.com/embed.js"></script>

var me = document.querySelector('script[src="//example.com/embed.js"]');

var me = null;
var scripts = document.getElementsByTagName("script");
for (var i = 0; i < scripts.length; ++i) {
  if (isMe(scripts[i])) {
    me = scripts[i];
  }
}

function isMe(scriptElem) {
  return scriptElem.getAttribute('src') === "//example.com/embed.js";
}

var scripts = document.getElementsByTagName('script');
var me = scripts[scripts.length - 1];
