Is a primitive type considered JSON?

Question

Most place the JSON is in format like

{
    color: \"red\",
    value: \"#f00\"
}

Or

[  
    { color: \"red\",     value: \"#f0         


        

Answer 1

The relevant RFC is RFC 7159, not RFC 4627. RFC 4627 is "informational". RFC 7159 is "standards track"; it explicitly obsoletes RFC 4627.

In the text of RFC 7159, you'll find this.

   This is a JSON object:

      {
        "Image": {
            "Width":  800,
            "Height": 600,
            "Title":  "View from 15th Floor",
            "Thumbnail": {
                "Url":    "http://www.example.com/image/481989943",
                "Height": 125,
                "Width":  100
            },
            "Animated" : false,
            "IDs": [116, 943, 234, 38793]
          }
      }
