With Google's never-ending mission of improving the performance of their Chrome/Chromium web-browser and their V8 JavaScript engine, the latest beta of the open-source web-browser now supports concurrent compilation of JavaScript in the background.

Yang Guo of Google noted in a blog post, "Historically, Chrome compiled JavaScript on the main thread, where it could interfere with the performance of the JavaScript application. In the latest Chrome Beta we've enabled concurrent compilation, which offloads a large part of the optimizing compilation phase to a background thread. The result is that JavaScript applications remain responsive and performance gets a boost."

The post goes on to talk more about the V8 JavaScript engine and how the concurrent compilation of JavaScript will mean a faster experience with JS-heavy web-pages. Those interested in learning more can read about the V8 multi-threaded improvement in the blog post. This beta with the background JavaScript compilation is for Chrome 33.
