Using number as "index" (JSON)

Question

Recently started digging in to JSON, and I'm currently trying to use a number as "identifier", which doesn't work out too well. foo:"bar" works fine, while 0:"bar" doesn't.

var Game = {     status: [                 {                     0:"val",                     1:"val",                     2:"val"                 },                 {                     0:"val",                     1:"val",                     2:"val"                 }            ] }  alert(Game.status[0].0); 

Is there any way to do it the following way? Something like Game.status[0].0 Would make my life way easier. Of course there's other ways around it, but this way is preferred.

JSON only allows key names to be strings. Those strings can consist of numerical values.

You aren't using JSON though. You have a JavaScript object literal. You can use identifiers for keys, but an identifier can't start with a number. You can still use strings though.

var Game={     "status": [         {             "0": "val",             "1": "val",             "2": "val"         },         {             "0": "val",             "1": "val",             "2": "val"         }     ] } 

If you access the properties with dot-notation, then you have to use identifiers. Use square bracket notation instead: Game.status[0][0].

But given that data, an array would seem to make more sense.

var Game={     "status": [         [             "val",             "val",             "val"         ],         [             "val",             "val",             "val"         ]     ] }
