Google Posts Round Up of Chrome Developer Improvements

Throughout the week, Google has been posting a lot of information from Google I/O on its various blogs. Today, they posted info from a presentation about how Chrome’s developer tools can improve productivity.

There was a whole lot to take it an I/O. Believe me I know. I was covering it. There are no doubt parts that you missed, so these posts can come in quite handy.

Google lists the following new and improved features for Chrome developers presented at I/O:

  • The Scripts panel now allows editing JavaScript without having to reload the page. Just double-click on the line in the function body while debugging and make your changes. We’ll patch the underlying optimized machine code at run-time and continue the execution. [video]
  • CPU profiler captures the state of your app at a rate of 1,000 samples per second without modifications to the running optimized machine code. The resulting tree view makes it easy to find out where to focus efforts on speeding up the web app. [video]
  • The new Timeline panel provides a simple view of the AJAX application execution. It records everything that happens in the browser from JavaScript execution to styles re-calculations and then visualizes it in a simple waterfall with timing information and traces to the source code. See the demo fragment at [video].
  • The improved Heap profiler can take snapshots of the JavaScript heap, visualize and compare them. This makes finding and fighting memory leaks a much easier task. See the demo fragment at [video].

You can also check out a video of a DevTools presentation in the blog post if you have 45 minutes to kill.
