Apple has released a new beta version of its Safari 4 Web browser with technology that the company claims makes it the world’s faster browser. Apple says it’s built on a new Nitro JavaScript engine that can execute code up to 30 times faster than IE 7 and more than three times faster than Firefox 3. And what about Safari 3? The Nitro engine in Safari will run JavaScript 4.2 times faster than the previous Safari build. There’s more than just a JavaScript speed boost. Safari 4 runs on both PCs and Macs, and it brings innovations from Mac OS X and even the iPhone to the browser.
