JSON and RSS feeds - difference?

What are the differences between JSON and RSS feeds?

Apart from:

A JSON feed is in a format that a JavaScript can easily开发者_高级运维 use directly.

Browsers can consume large amount of JSON much more efficiently than they can consume large amount of XML and the gap is widening because the latest versions of the browsers are now providing native, safe support for encoding and decoding JSON.

If you are using JavaScript then you know what a hassle the DOM can be. I would suggest using JSON just because it is easier to program for. I also depends on where you are sending it, whether or not your clients support RSS or JSON.

Other things:

• JSON is easier to debug visually
• Lots of good libraries for JSON in server side languages
• More compact than RSS
• You can define your own api/protocol (RSS is a standard)

JSON's substantially easier to parse. In PHP, for example, it's just json_decode($json).
