Just do object...

var dict = { 'key': 'value', 'answer': 42 };

alert(dict['key']); // output "value"
alert(dict.answer); // output 42

dict.key = 'forty two';
dict['answer'] = 0;
dict.newkey = "new value";

alert(dict['key']); // output "value"
alert(dict.answer); // output 42
alert(dict['newkey']); // output "new value"
