> personal opinion I take it you didn't read my original comment? Also I disagree, dangling comma is a visual cue that the sequence has a continuation.

  >Also I disagree, dangling comma is a visual cue that the sequence has a continuation We already have a mechanism for telling whether a sequence ends or not -- the opening and closing bracket for the sequence. No need to have a second redundant one. This way the last element is an ordinary part of the sequence as any other and doesn't need a special exception to its formatting like the omission of the comma. Besides the point is moot as the "dangling" comma is already part of the JS standard.

    You're talking about syntactic rules, I'm talking about visual cues. IMO there is no reason to have commas at all so this discussion is pointless.

      >You're talking about syntactic rules, I'm talking about visual cues. In what way is ] also not a visual cue?
      • keymone 9y ago
        In what world having multiple cues with opposite meanings is considered good?
        • coldtea 9y ago
          In what world is the "," at the end of the final line an "opposite meaning" to ]? Not on modern JS world, which allows for dangling , everywhere: http://2ality.com/2013/07/trailing-commas.html http://2ality.com/2013/07/trailing-commas.html, so having a "," doesn't mean the line is not the last one anymore, just means "it's a line like any other". It's time JSON gets up with the times -- especially since it's a totally backwards compatible improvement.

            > it's a line like any other yeah, in other words - there should be no commas whatsoever. Weren't you the one complaining about redundancy?
