And you are here why?

Great articled on Sealed Abstract on this . Go read the whole thing - its long (10K words!), but completely absolutely worth it. The conclusion is fairly straightforward (and depressing) So here’s what you should remember: Javascript is too slow for mobile app use in 2013 (e.g., for photo editing etc.).   It’s slower than native code by about 5 It’s comparable to IE8 It’s slower than x86 C/C++ by about 50 It’s slower than server-side Java/Ruby/Python/C# by a factor of about 10 if your program fits in 35MB, and it degrades exponentially from there The most viable path for it to get faster is by pushing the hardware to desktop-level performance.  This might be viable long-term, but it’s looking like a pretty long wait. The language itself doesn’t seem to be getting faster these days, and people who are working on it are saying that with the current language and APIs, it will never be as fast as native code Garbage collection is exponentially bad in a ...
