Chrome Dev Tools: JavaScript and Performance | Nettuts

In this third part of our Chrome Developer Tools series, we’ll review how to modify and debug JavaScript. Optimization is an important part of the development process, especially for performance-critical applications. We’ll also discuss techniques for identifying potential bottlenecks in our code.

As in the previous two articles, I’ll be focusing on the features found in the Chrome Canary build (version 26.0, as of this writing). I’ll cover the Sources and Timeline panels.
