7 days ago, Jason Orendorff checked in a new feature to the JavaScript engine, the Map constructor.  His timing could not have been better for me, as I was just finishing up a critical part of my DimensionalMap project: getting all tests passing with WeakMaps for object keys.  (DimensionalMap is about a JavaScript-based hashtable in two or more dimensions.)  It didn’t take me long to create a “nativemap” branch and convert my code to work for keys of all types.

That alone would have been cause to celebrate.  I figure Jason’s work here shaved a couple of months off of this project.

However, thanks to Olli Pettay, Jonas Sicking, Ben Bucksch, and Dão Gottwald, among others, my patch for adding timeout support to XMLHttpRequests landed on Thursday.  DOM Workers support for timeouts will have to wait a bit longer, as I’m still a little busy and workers require special JSAPI incantations which I have not yet mastered.  Help wanted!

It feels nice to see both of these happen.  I haven’t been able to contribute much code to Mozilla lately, so anytime I can get something meaningful in, it’s a good week.
