I’ve been messing around with JSON for some time, just pushing it out as text and it hasn’t hurt anybody (that I know of), but I’d like to start doing things properly.

I have seen so many purported “standards” for the JSON content type:

application/json
application/x-javascript
text/javascript
text/x-javascript
text/x-json

But which one is correct, or best? I gather that there are security and browser support issues varying between them.

I know there’s a similar question, What MIME type if JSON is being returned by a REST API?, but I’d like a slightly more targeted answer.
