› New JavaScript engine coming to Chrome
  • Published on February 20, 2014

Hypertext Markup Language, more commonly known as HTML, is the primary language of the Web. If you want to learn how to write your own webpages, HTML training at the American Graphics Institute can help you master the fundamentals of this powerful markup language and begin creating your own websites from scratch. Of course, after a while, you might decide to bolster your coding knowledge by learning JavaScript, a dynamic programming language that is used to provide websites with greater functionality. Recently, Google announced that it would incorporate a new JavaScript engine to improve the speed of its Chrome Web browser, PC Pro reported.

Under the hood
Chrome is already one of the fastest browsers available, and performs consistently well in benchmarked speed tests. However, the engineers at Google aren't content with the browser's current performance, and have made substantial tweaks to Chrome's underlying JavaScript engine to reduce latency, or the time it takes for routine tasks to be completed. 

The way in which JavaScript code is read and executed by the browser lies at the heart of the new engine. In short, the new version of the V8 JavaScript engine will compile and execute code simultaneously, resulting in significant improvements to performance and speed.

"To reduce the overall time spent compiling, V8 defers compilation of JavaScript functions until immediately before they are executed the first time," Yang Guo, an engineer on the V8 project, wrote in an official blog post. "This compilation phase is fast but doesn't focus on optimizing the code, just on getting it done quickly. In V8, pieces of code that are executed very often are compiled a second time by a specialized optimizing compiler. This second compilation pass makes use of many advanced optimization techniques, meaning it takes more time than the first pass but delivers much faster code."

Significant potential
So, what does all this mean? Well, if you've ever spent minutes waiting for Chrome to respond on a mobile device, you'll probably be interested to learn that these improvements to the V8 engine mean that Chrome performs significantly better on Android smartphones. In fact, according to Guo, benchmark tests showed a speed increase of 27 percent during initial testing, meaning that pages will load much faster using the new concurrent compilation system.

Professionals in a wide range of roles, from marketing to sales, can benefit from understanding the language of the Web. If you're ready to embark upon your own journey to the heart of the Internet, taking HTML training at the American Graphics Institute is an excellent first step.
