Thanks. Beside JavaScript, I use another programing language too where JSON is supported. During a data import (data in JSON format) I found a typo in my imported data, but the import was without any error message. What the heck is that, I thought, and started some digging... Here are the results, and I'm stumped. The html file (see below) was opened with Google Chrome. The output (see below too) looks a little bit buggy, but I think, the staff at Google will know, what they do, so there must be some kind of explanation for this output. Is there someone here who can enlighten me? Thank you, Julius --- the html-file --------------------------

--- end-of-html-file -------------------------------------- --- the-output -------------------------- [ 11,, null] --> Unexpected token , in JSON at position 5 [11,null,null] --> empty field (,,) is parsed! array-size: 3 --> nonexistent (undefined) items are counted 0 number 1 undefined 2 object --> FOR loop is executed 3 times 0 number 2 object --> The loop is executed 2 times! [11,null,null] --> [11,undefined,null] Stringify vs. content. Which one is correct? --- end-of-output ------------------------------------- -- An old Windows has old security holes.
