How Does Your Web Browser Handle JavaScript?

Google Chrome has been officially in beta for about a month now. Many of you are using it for your default browser already at this point. I wrote about Google Chrome this month for my CPU Magazine article. I want to discuss one of those points with all of you now.
As you visit websites, you may seem to be slowed down due to the amount of script that is running on the page. It’s all potentially tied into JavaScript performance. This is going to get interesting in a couple of months. Google has said they will be using the V8 JavaScript engine. This, of course, is now a part of WebKit. Just last week, WebKit came out and said they have SquirrelFish Extreme, which is a register-based, direct-threaded, high-level bytecode engine, with a sliding register window calling convention. It lazily generates bytecodes from a syntax tree, using a simple one-pass compiler with built-in copy propagation. This increases JavaScript performance even more, even compared to V8.
We’re about to enter a browser war, specifically in the area of JavaScript performance. Google releases a beta browser, with a good JavaScript engine. Let’s face it, a lot of your favorite sites are probably running JavaScript right now. And, Chrome is handling it much more efficiently. Here we have a Beta browser who is running a better JavaScript engine than what any of the current leading browsers have. This is raising the bar in a very big way for everyone else.
I went searching the web to help me find something that can help me download the nightly build of the WebKit. I found NightShift for use on Mac OS X. NightShift automatically downloads and updates WebKit, the Safari HTML rendering engine, to the latest nightly version for Safari. No user intervention is required, everything is fully automated. The developer has a few other cool tools, as well.
For Windows users, check out Chrome Plugins. This site is full of Plugins, Themes, Add-ons and information for the Google Chrome Web Browser! This isn’t an “official” Chrome blog, but the people who are working officially on Chrome are a part of this community, as well. You can learn pretty much everything you need to know about Chrome, and then some!
What are your thoughts? Where do you think browsers are heading?
