ECMAScript Edition 4 Reference Implementation
Category: JavaScript
You can download the reference interpreter as well as checking out the documentation.
Brendan Eich blogged about the release:
As Dave notes, this is a “pre-release” in the Open Source, “release early and often” sense. We are not done yet, but the Reference Implementation passes over 90% of the ES3 tests that we host in cvs.mozilla.org. I should note here that the Reference Implementation already handles a great deal of ES4 in addition to most of ES3, so for example the self-hosted built-in classes are mostly there.
…
This is just the beginning. Our plan is to finish the Reference Implementation over the summer and then work on specification language to surround pretty-printed excerpts of the SML and self-hosted ES4 code. At the same time, Mozilla, Adobe, and anyone who wants to help will bring up the new language on Tamarin in the new Mercurial repository. I’ll have more to say about that in a bit.
