Storing dynamic dates in javascript

Question

I wish to store if a specific date is loaded via Javascript. How this boolean is saved/accessed has no difference, however I'm not sure as to what the best solution is performance-wise.

I could know I could store it like this and loop through each object, however I guess this wouldn't really be efficient. var loaded = { {d:23, m:11, y:2012}, {d:24, m:11, y:2012} };

Another idea I have is to store this in an array, like so: loaded[2012][11][23] = true;

But I'm sure there are better ways to accomplish this, so I'd appreciate any guidance

Unless you have to list available years, available months or available days, you could always use an Object as a dictionary for storing dates as UNIX timestamp numbers (which you can convert to and from Date objects) or "YYYYMMDD" strings.
