ECMAScript Edition 4 Reference Implementation | Lambda the Ultim. The first pre-release of the reference implementation of ECMAScript Edition 4 (a.k.a. JavaScript 2) is now available.
We've created a new web site for information about the ECMAScript specification and reference implementation. You can download source and binary forms of the reference implementation. As we've discussed before here on LtU , the reference implementation of ECMAScript is being written in Standard ML. This choice should have many benefits, including: to make the specification more precise than previous pseudocode conventions to give implementors an executable framework to test against to provide an opportunity to find bugs in the spec early to spark interest and spur feedback from the research and user communities to provide fodder for interesting program analyses to prove properties of the language (like various notions of type soundness) to use as a test-bed for interesting extensions to the language.
