comments in JSON?

The grammar on www.json.org does not define any comments at all.

i have tried with {"name": "value" /* comments */ }, it is ok, but
{"name": "value" // comments } does not work.

With
{"name": "value" // comments }
on one line the // comments out the closing brace '}' so that object
literal lacks the closing brace.

Maybe it depends on the comment being the last thing on the line. As
in, perhaps // is killing the }.

var obj1 = {
attr1 : 'the first attribute',
attr2 : 'the second attribute', // works!
attr3 : 'the third and final attribute' /* works! */
}

The second does indeed create a comment. The reason it "does not work"
isn't because of the comment itself, but, because the comment goes from
// to the end of the line and that, in turn, "eats" the } and causes a
syntax error:

{"name":"value"}//This comment will "work"

You don't get an error with the first one because the comment goes from
the opening to the closing comment de-limeters and doesn't "eat" the }
after it because the */ closes the comment.
