Is the order of elements in a JSON list preserved?

Question

I\'ve noticed the order of elements in a JSON object not being the original order.

What about the elements of JSON lists? Is their order maintained?

Answer 1

The order of elements in an array ([]) is maintained. The order of elements (name:value pairs) in an "object" ({}) is not, and it's usual for them to be "jumbled", if not by the JSON formatter/parser itself then by the language-specific objects (Dictionary, NSDictionary, Hashtable, etc) that are used as an internal representation.
