I am curious about the semantics of the MIME types application/javascript versus text/javascript.

Obviously,Apart from the obvious - one is supposedintended to be executed, and the other is supposed to be just text.

I see application/javascript when looking at headers of an external .js load.

If this application/javascript will execute the javascript, why don't we use

<script type="application/javascript">
  // some js code.
</script>

And vice-versa, why is an external js load not text/javascript?
