Chakra Building a new JavaScript

A talk by Pete LePage

About the Talk

September 25, 2010 1:15 PM

Over the last five years, JavaScript has gone from a language for adding interactivity to a key driver for innovation on the web. A new generation of applications such as Gmail and Office Web Applications use thousands (or hundreds of thousands) of lines of JavaScript to deliver functionality and complexity similar to traditional desktop applications. With the advent of AJAX and script libraries, nearly every new site today makes use of JavaScript. These changes have also pushed browsers and script engines to evolve rapidly to keep up with user and developer needs to have fast, responsive applications and sites.

Internet Explorer 9 introduces a new JavaScript engine, codenamed Chakra, which fundamentally changes the performance characteristics of JavaScript inside Internet Explorer 9. We'll dive into what's new in Chakra, including the new compiler that compiles JavaScript source code into high-quality native machine code, a new interpreter for executing script on traditional web pages, and improvements to the JavaScript runtime and libraries like ECMAScript 5 support.
