jsfiddle-integration-babel.js 的目的是什么？

Question

的目的是什么

<script src="https://facebook.github.io/react/js/jsfiddle-integration-babel.js">
</script>

在 Facebook 的 React 教程中找到 fiddle？

jsfiddle-integration-babel.js的内容是

(function() {
  var tag = document.querySelector(
    'script[type="application/javascript;version=1.7"]'
  );
  if (!tag || tag.textContent.indexOf('window.onload=function(){') !== -1) {
    alert('Bad JSFiddle configuration, please fork the original React JSFiddle');
  }
  tag.setAttribute('type', 'text/babel');
  tag.textContent = tag.textContent.replace(/^\/\/<!\[CDATA\[/, '');
})();

看起来 tag 跟踪脚本并从中删除某些评论。但是为什么？

Presumably this is to make the jsfiddle environment babel friendly, which may imply overriding existing jsfiddle code
