sad that nobody writes anything in this blog anymore :(( because Chakra is quite fascinating engine, yet most people never even heard about it ...

@John A. Bilicki III:

The IE9 WILL NOT be available for an OS that's older than 10 years. Plus: even if Microsoft would do this they had to port the whole graphics engine to XP. Meaning to run IE9, you have to have DirectX11 installed. An uprade would be the size of at least another SP, maybe 1-2GB and any OEM vendor had to check their drivers again (espeacially for laptops).

I don't know why some people just say 'this and that has to be done' but don't know anything about the whole thing.

According to the IEBlog, ES5 will be heavily integrated into IE9. And it looks like it will not be available outside the browser as a generic scripting engine (called now JScript). Can someone confirm this?

Ok, I'll stay tuned.

Even if many work have been done with JScript for IE8, many work is still to be done (IE8 is the less ES5-compilant browser regarding to your set of ES5-tests about new major changes from ES3; IE8 is the slowest browser on JScript performance tests (SunSpeeder & others), ...)

You've got a great challenge and a lot of things to explore : hard but funny work [;)]

A testsuite makes realy sense! Good work... but....

please apply professional javascript coding practices (don't pollute the global namespace, use something like jsDoc, ...)!

Theorically, it should not change anything to normal JScript use. They have added new features and clarified some border-edge cases, but you don't need to modify your scripts to make them ES5-compilant.

The test suite is only useful to test the browser’s compliance or can the end user’s application javascripts could also be tested through these tests? It will be great to have a TestSuite or tool, that can parse through all the javascript code used by end user applications and be able to find some potential issues (if any) when we migrate towards ECMAScript5.
