if html5 sucks then why is adobe thinking of moving to it? [Quote from wikipedia] "In November 2011 Adobe announced the end of Flash for mobile platforms or TV, instead focusing on HTML5 for browser content and Adobe AIR for the various mobile application stores.'

He mentions no available frameworks, but what about ImpactJS? Was this made before ImpactJS?

Link the benchmarks then, please. At my research, what you consider "near C performance" was 7 times slower in the best case (1700 in the worst). Sorry but that doesn't impress me at all. Imagine trading you 3 ghz processor for 430 mhz one, and that was the best case I could find. As I said in the other comments, there are several limitations in javascript that, while convenient, make the language slower. It's NOT best language to a server side game application and it's slower than c. Period.

Or you could realize that this guy knows his stuff, and take a second or two to research the issue, and find this snippet from '08 on infoq "The Mozilla Foundation has developed TraceMonkey a trace-based JIT compiler that pushes the envelope on JavaScript performance. With plans to be incorporated it in the 3.1 release of Firefox, it delivers near C performance and promises to 'leap frog' RIA development to a new level."

I like async socket io,.., but thats something to do with low level network IO, php is only content generation,..., so the two are totally seperate,..., the argument he makes is bullshit.

and for everything else you can use a native client like minitube.

turn on html5 videos on youtube, it's been working well for quite a while now(although certain videos aren't yet encoded in WebM)

I've uninstalled the flash plugin more that 4 months ago. And I'm watching this video. An increasing number of videos are available without the flash plugin in pure HTML5 (april 2012)

JIT is an improvement, that can't be denied, but it is still slower than compiled, machine optimized code produced by C. Also, there are other features that will make it slower such as garbage collecting, heritage (if using OO) and exception handling. Taking python for example (~1000 times slower than C, same performance limitations), JIT optimizers make at most the code 33 times faster (last time I checked), still AWAY slower than C.

I wouldn't call dynamic typing a limitation, but from a performance standpoint, yes, it does make things a bit slower. Hence the words "almost as fast". But the use of an interpreter is just an implementation choice, and modern JS implementations are not interpreted. They are JIT-compiled to native code, and that's where the speed comes from.
