A recent hire in Apple's WebKit development team has come up with a new Low-Level Interpreter (LLInt) that can do much more processing of JavaScript code in WebKit's JavaScriptCore before handing it off to the Just-In-Time (JIT) compiler or bytecode virtual machine, realizing a speed gain of over 200 percent compared to the current model. The "triple-tier" approach will result in more fluid animations and faster programatic web applications, widgets and more.
