How to properly investigate when you encounter mysterious browser freezes.

I’ve been tinkering with Node.js recently, following along with “Node.js in Action” to implement the Microblog project. Since the book was written in 2012, and Node has since been updated to v5.9.0 with Express also having undergone significant changes, much of the code in the book no longer works with current versions. For the implementation details, you can refer to this article: “Node.js Development Guide” Microblog Example with Express 4.x. BTW, the Express startup command has changed to npm start, which executes the www file in the bin directory, equivalent to running node ./bin/www directly. This post briefly covers the logging and multi-core CPU optimization topics mentioned in Chapter 6, along with an introduction to a debug tool.
