Question

What exactly is the difference between an object and a dictionary in Actionscript?

var obj:Object = new Object();
obj.something = "something";

var dict:Dictionary = new Dictionary();
dict.something = "something";

trace(obj.something, dict.something);

The trace statement seems identical…

I think the example here highlights at least one of the most significant differences, which is strict equality in comparing keys.

In summary, dictionary[key] does NOT necessarily return the same value as dictionary[“key”], even if key.toString() equals “key”.

However, object[key] will return the same value as object[“key”], if key.toString() equals “key”.
