saying that javascript is fast doesnt make sense.
Is it faster than 5 years ago sure. But the amount of work on needs to do have good performances is just silly. Is it everywhere ? sure. But i've seen a lot of crazy JS demos , i'm running a decent machine ( Macbook pro) and sorry but most of the exemples i see have poor perfomances , and nothing close to native performances. So imagine a soft you need to use 6 hours a day , you'll feel the bad perfs , trust me.
So please let's stop saying javascript is fast, it is a lie. Speed is not something absolute , it is relative. It is slower than native and will always be. Native will always be easier to optimize too.
Doesnt mean we cant do anything in html5/js , just mean we cant do everything. And the more "special" feature one uses the less "compatible" the js app will be.
Now is ASM a good thing sure. But let's not fool people just to promote JS.
