Prototype JS Hash Table alternative/solution for Jquery

Question

Hi everybody I'm a prototype js developer and I'm moving for work/client reasons to jquery. I'm a big fan of Prototype Hash var h = new Hash(); class I know that in jQuery is not any hash table available at least in the core, I would like to know what it the best alternative to have a good practice/solution in a way to manage my data structure in a pretty same way as I do it with the hash table? of course using Jquery.

normally I'm storing objects in the way { name : "myname", photos : ["1.jpg","2,jpg"], and : "so on"} basically what I do is ask for specify id in my hash table and retrieve the specific object of that id. for example if I have a list of user in a webpage and an user with id = 3 is clicked. I asked for h.get(3) => { name : "", bla bla}. — ncubica

You can use an object for that, too: jsfiddle.net/minitech/NJpSB — Ry-

If you're only using strings as keys, you can use a plain old object (since you're no longer using Prototype, you don't have to worry much about overwriting things):

var h = {};
h.somekey = somevalue;
h.someotherkey = someothervalue;
h[dynamickey] = val;

I think I could do something like var h = {}; $.each(jsonResponeList,function(index, item){ h.item.id = item; //I dont know if this is posible hahaha }

@nahum: Certainly it's possible: h.item = { id: item };
