Recommend text/javascript as the media type for JavaScript resources

[alrra]

Servers should use text/javascript for JavaScript resources. Servers should not use other JavaScript MIME types for JavaScript resources, and must not use non-JavaScript MIME types.

Ref:

• Require servers to use text/javascript whatwg/html#3096
• Register some more JavaScript MIME types bmeck/I-D#2

I dont think this change is correct

https://www.iana.org/assignments/media-types/application/javascript = OBSOLETE
https://www.iana.org/assignments/media-types/text/javascript = COMMON

@gemal Historically, text/javascript was recommended and used since the early days, so the chances of it breaking things is less than the recently IANA recommended application/javascript.

The HTML spec was also updated and recommends using text/javascript (and usually the spec tries to reflect the reality, not some ideal world).

Note: For current user agents it shouldn't matter that much which of the two you use, but with this project we try to recommend what is considered the best option.

Hope that clarifies things.

This document updates the existing media types for the ECMAScript programming language. It supersedes the media types registrations in [RFC4329] for "application/javascript" and "text/javascript".

But this said text/javascript is obsolete
