Is there a way to use an ko.observableArray like a map/dictionary?

For example:

var arr = ko.observableArray();
arr.push('key', { '.. Some object as value ..' });

And then retrive the value using the key:

var value = arr['key'];

• Have you checked out this guy's dictionary implementation? github./jamesfoster/knockout.observableDictionary – Tom W Hall Commented Oct 21, 2012 at 11:34
• @TomHall: Thanks for the link, it looks good. I've found another more naive implementation: wiredprairie.us/blog/index.php/archives/1563 – MichaelS Commented Oct 21, 2012 at 11:37

Found two possible implementations:

1. James Foster / knockout.observableDictionary - It has everything a dictionary needs. (Thanks to Tom Hall for the great find)
2. A more naive implantation - suits the basic needs.

I ended up using the observableDictionary, it is fast and simple.
