Is it Internet Explorer? I heard that JScript.NET was there for a long time and with .NET, things can be JIT'ed. Are we going to see JIT'ed javascript in IE soon?

The slowest Javascript Implementation in Browser Is it Internet Explorer?
JScript is somewhat slow. However, I'm not sure it is the slowest. There's dozens of JavaScript engines, it's pretty likely that there's one even crappier than JScript.
Although, it is hard to beat implementing objects as linked lists. That is probably the stupidest thing I've ever heard.

JScript.NET is faster than JScript, but Microsoft only allows you to use it on the server in ASP.NET, you can't use it in the browser.

The Chakra engine in IE9 does JIT compilation. In fact, it is probably the fastest JavaScript engine right now, although benchmarking unreleased development code against stable releases is always unfair.

Look at the comparisons with IE9, they have made improvements that you can test out with the developer release. – James Black – 2010-06-03T14:41:24.167
Actually, what I am after is would there be a built-in javascript engine (just like the COM based Windows Scripting Host) available from Windows in the near future. Because I am now considering the best way to embed a efficient Javascript engine in my own appli.
I can use the current COM based JScript (or VBScript) engine from Windows directly but it seems to be too slow for my need. What I am after is something as fast as V8. – None – 2010-06-03T14:44:01.717
