How to convert an Object {} to an Array [] of key-value pairs in JavaScript

Question

I want to convert an object like this:

{\"1\":5,\"2\":7,\"3\":0,\"4\":0,\"5\":0,\"6\":0,\"7\":0,\"8\":0,\"9\":0,\"10\":0,\"11\":0,\"12\":0}

Answer 1

Use for in

var obj = { "10":5, "2":7, "3":0, "4":0, "5":0, "6":0, "7":0,
            "8":0, "9":0, "10":0, "11":0, "12":0 };

var objectToArray = function(obj) {
    var _arr = [];

    for (var key in obj) {
        _arr.push([key, obj[key]]);
    }
    return _arr;
}

console.log(objectToArray(obj));
