Debugging

Q: How deeply does Secrets of the JavaScript Ninja, Second Edition cover debugging?

Compares browser-tool capabilities but leaves specific debugging techniques for later.

As explained in Secrets of the JavaScript Ninja, Second Edition

The process of finding, inspecting, and correcting software defects or unexpected behavior.

When a web application behaves unexpectedly, debugging means investigating its JavaScript and browser behavior. Browser developer tools offer a richer alternative to checking values with alerts. section 1.3.1 section 1.3

Choose the developer tools available in the browser where you are investigating the problem:

Firebug for Firefox; Chrome DevTools for Chrome and Opera; Firefox Developer Tools; F12 Developer Tools for Internet Explorer and Microsoft Edge; or WebKit Inspector for Safari. section 1.3.1
These tools share capabilities for exploring the DOM, debugging JavaScript, editing CSS, and tracking network events. Some, including Chrome DevTools, can also debug Node.js applications. section 1.3.1
