Question

I have an Array that looks like this

[["BR",1],["USA",2],["CH",3]]

and I want to convert it to something like this

{"br":1,"usa":2,"ch":3};

Any clues?

Thanks guys

var len = arr.length, i, hash = {};
for (i = 0; i < len; i++) {
  hash[arr[i][0].toLowerCase()] = arr[i][1];
}

This will convert into an object. You can use JSON.stringify(hash) in newer browsers, or if you use a library like jQuery, to make it into a JSON string. Writing JSON by yourself is somewhat error-prone, best leave it to builtins and libraries.
