There is no dependency any more, and the subset relationship has already been destroyed by the introduction of Line/Paragraph separators (U+2028/U+2029) in recent versions of ECMAscript (these are valid in JSON strings but not in ECMAscript 5 strings). It is best to acknowledge the role of JavaScript as the inspiration for the JSON data interchange format (and one of its biggest customers), but otherwise consider the two specifications independent of each other.
