[Dynapi-Dev] JIT JavaScript (was My JS Optimization Site)

[Erik A. <er...@ea...>]

What made you think that MS has a JIT for JScript? Personally I thought this
was one of the good news about .Net and JScript.Net. (Getting the same
performance as from all other languages.)

IE3+ has been using MS JVM which uses JIT but this does not mean that
JScript benefits from this?

Any proof / hints really apreciated. Same goes for Netscape Navigator 4 and
Mozilla 5.
