This chapter introduced many concepts for profiling and debugging our code. It took into account the various modern browsers that are out there and even the special features that each of them may or may not have. We specifically looked at the Chrome browser, since a good many developers use it as their main development browser. In addition to this, the V8 engine is used in Node.js, which means all of our Node.js code will use the V8 debugger. Finally, we took a look at utilizing jsPerf to find out what may be the best implementation of some piece of code. We even looked at the possibilities of running it in our own system and how we can implement this.
Looking forward, the remainder of the book will not specifically talk about any of these topics in such detail again, but these tools should be used when developing the code for the rest of the book. On top of this, we...
