MIME (Multipurpose Internet Mail Extensions) types identify file formats on the web. They tell browsers how to handle files.
What's the MIME type for JSON?
The correct MIME type for JSON is "application/json". Some older systems use "text/json" but this is deprecated.
Why does the same extension have multiple MIME types?
Some extensions (like .xml) can have different purposes, each with its own MIME type for specific use cases.
