Difference between application/javascript and text/javascript

Question

I was reading a tutorial on HTML 5 Canvas Animation with javascript (of course). In the header, the author used
application/javascript which is rather new to me because I've only seen text/javascript used. Can anyone help? There is every likelihood this question has been asked before but I'm using a phone to do this so I can't see any similar questions.

Thanks

I don't know the difference but I know that HTML5 default value for type attribute on script element is text/javascript w3.org/TR/html5/scripting-1.html#attr-script-type — pomeh

And someone could use also application/x-javascript. Anyway, the browsers are tolerant and it might no matter. — antonjs

text/javascript - is obsolete
application/javascript - MIME type for JS

Guidelines:

Use application/javascript on the server to return MIME type
Use text/javascript for type attributes of <script> tag although it's not really required

application/javascript is the correct MIME type for Javascript, although text/javascript shouldn't cause any issues
