Mozilla & Gecko clones "Firefox OS could actually be wildly successful, no matter how underwhelming the actual phones may be. And that's because - at least for now - you're not the customer; your carrier is." I'm extremely disappointed by Firefox OS so far. There's nothing wrong with the low-end hardware we've seen during MWC, but there is something wrong with low-end hardware that can't even properly run its operating system. To make matters worse, carriers are the boss here. Terrible first impression.

It depends a lot on what you're doing, for applications with a heavy computational factor it most certainly won't (though matching Java/C# is not impossible in JavaScript). For applications leveraging the runtime more it can be every bit as fast as a native application from the user perspective.


You just don't know enough about the executing code to do meaningful code optimization, and are running under time constraints as the code gen is happening in real time. This is in contrast to the case with C#, especially as moondevil mentioned, where compilation is done offload and gratuitous optimizations can be applied.


It is improving and some of the latest optimization frameworks being introduced @Mozilla are specifically geared towards actual web apps rather than regular web pages (the IonMonkey JIT for example).


Mozilla being on its Nth JavaScript engine doesn't really impress me as much as it once did.

Just take a look at https://developer.mozilla.org/en-US/demos/detail/bananabread and then please comment on whether you still think that JS JITs can't do "meaningful optimizations".

You mean a 1996 game quality in 2013 where the GPU is doing most of the real work, yeah really impressive.

Impressive, and JS has come a long way, but it is a little silly to argue for its merits for CPU bound performance by using a GPU bound game with yesteryear graphics.
