Answer 1

An old question but I recently needed to do an AS3>JS port, and for the sake of speed I wrote a simple AS3-style Dictionary object for JS:

If you didn't know, the AS3 dictionary allows you to use any object as the key, as opposed to just strings. They come in very handy once you've found a use for them.

It's not as fast as a native object would be, but I've not found any significant problems with it in that respect.

API:

//Constructor
var dict = new Dict(overwrite:Boolean);

//If overwrite, allows over-writing of duplicate keys,
//otherwise, will not add duplicate keys to dictionary.

dict.put(key, value);//Add a pair
dict.get(key);//Get value from key
dict.remove(key);//Remove pair by key
dict.clearAll(value);//Remove all pairs with this value
dict.iterate(function(key, value){//Send all pairs as arguments to this function:
    console.log(key+' is key for '+value);
});


dict.get(key);//Get value from key
