HTML script tag completion uses obsolete syntax

#1

On starting to type <script>, in HTML syntax, pressing autocomplete causes the following code to appear:
<script type="text/javascript"></script>
However, the type text/javascript is obsolete. This was used in the early days of Html.
The correct content type to use in browsers is application/javascript. This helps browsers accept the content as JavaScript code.

Source?

From MDN (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script), I think text/javascript is good.

The topic is discussed at

While MDN still points to text/javascript, the linked IETF RFC marks it obsolete and suggests application/javascript.

I’d just call it another example of standards vs. reality.

Interesting that RFC is published in 2006…

But at the same time from the same SO answer:

So the bottom line is that the type=“text/javascript” doesn’t do anything as far as the javascript is concerned, but it’s part of the spec for both HTML 4 and XHTML 1.0 .

There seems to be no point to use application/javascript nowadays as

  • if we want to support HTML 4 browser, then text/javascript.
  • if we want to support HTML 5 browser, then no type is needed. (see the same MDN link)
