JSON does not support comments, as it is designed to be a data interchange format, not a programming language. This means that any text that is not part of a JSON object or array is considered invalid and will cause parsing errors.

If you need to include comments in your JSON file, one workaround is to use a string property to store the comment. For example:

{
 "name": "John",
 "age": 30,
 "comments": [
   "This is a comment",
   "This is another comment"
 ]
}

In this example, we have added a `"comments"` property that is an array of strings, where each string represents a comment. While this is not a true comment syntax, it allows you to include additional information in your JSON file without causing parsing errors.

Another option is to use a separate file to store comments or include them in documentation outside of the JSON file itself.
