Javascript Data Structures

How can I store player names and scores in a way that is easy to set, retrieve and update? Arrays, objects etc? What are the pro's and con's? Which is more e开发者_如何学Goxtensible?

I was thinking something like

Players {
    [Dan : 500]
    [Jess: 600]
    [Elvis: 56]
}

Key-value stores in Javascript are objects:

var players = {
    Dan   : 500,
    Jess  : 600,
    Elvis : 56
};

players.Dan = 300;
alert(players.Jess);

var Players = {}; 

// adding new player.
Players["Dan"] = 0; 

// push score
Players.Dan += 10; 

Objects have an advantage over key-value pairs in that they are extensible. You can store more attrbutes

Objects would serve your purpose :

eg:

var players = { "Dan" : 500 , "Jess" : 600 , "Elvis" : 56 }

You can easily access values using key.

eg

alert(players["Dan"]);
