Can comments be used in JSON?

Can I use comments inside a JSON file? If so, how?

The JSON is data only, and if you include a comment, then it will be data too.

You could have a designated data element called "_comment" (or something) that should be ignored by apps that use the JSON data.

You would probably be better having the comment in the processes that generates/receives the JSON, as they are supposed to know what the JSON data will be in advance, or at least the structure of it.

But if you decided to:

{

   "_comment": "comment text goes here...",

   "glossary": {

      "title": "example glossary",

      "GlossDiv": {

         "title": "S",

         "GlossList": {

            "GlossEntry": {

               "ID": "SGML",

               "SortAs": "SGML",

               "GlossTerm": "Standard Generalized Markup Language",

               "Acronym": "SGML",

               "Abbrev": "ISO 8879:1986",

    "GlossDef": {

                  "para": "A meta-markup language, used to create markup languages such as DocBook.",

                  "GlossSeeAlso": ["GML", "XML"]

               },

               "GlossSee": "markup"

            }

         }

      }

   }

}
