Javascript is great for tweaking web pages but people just don't know when to stop. If you look at a news site you'll see tens of kilobytes of JS code; a lot of that code's trying to figure out who you are and what you're doing (its Phorm written in JS....). This not only slugs the browser but causes browser crashes when different sites start fighting over your browser.

NoScript helps but something like a JS analog to Adblock Pro would be better.

The last thing we want is for people to make JS perform faster....that'll only encourage the Omnitures of this world.

This technique has been widely used in emulators since the ZSNES, but it was called Dynamic Recompilation.
Definitely the way to go, but think about it - creating machine code on the fly means that you cannot use the Non-Execute bit on your data memory area.

from reading the article, i have deduced that java and javascript are the same thing...

w00t

That's nice. Now they only have to make Firefox 3 stable on Windows for me to switch back.

Just to be clear, because the title of this article is misleading, JavaScript is NOT Java.

Javascript != Java

Come on, which is it? Java or Javascript? Own up.

This article needs some editing. The sentence at the end doesn't make a lot of sense, and it's about JavaScript, not Java. They're two completely separate technologies.

Java and JavaScript are unrelated entities. A speedup in one has no bearing on the other.

JavaScript != Java

It'd be interesting to see a Firefox 3.1 TraceMonkey speed test against Safari 4.0 SquirrelFish.



why not just use opera, java's well supported, write your own scripts :O)

And why does your subhead say "does Java better"?
