Can comments be used in JSON?

⬅️ JSON 🔗 Stack Overflow

No. JSON is data-only. If you include a comment, then it must be data too.

A hack!

{
  "api_host" : "The hostname of your API server. You may also specify the port.",
  "api_host" : "hodorhodor.com",
 
  "retry_interval" : "The interval in seconds between retrying failed API calls",
  "retry_interval" : 10,
 
  "auth_token" : "The authentication token. It is available in your developer dashboard under 'Settings'",
  "auth_token" : "5ad0eb93697215bc0d48a7b69aa6fb8b",
 
  "favorite_numbers": "An array containing my all-time favorite numbers",
  "favorite_numbers": [19, 13, 53]
}

The above code is valid JSON. If you parse it, you’ll get an object like this:

{
    "api_host": "hodorhodor.com",
    "retry_interval": 10,
    "auth_token": "5ad0eb93697215bc0d48a7b69aa6fb8b",
    "favorite_numbers": [19,13,53]
}
