When used effectively, JavaScript debuggers help find and squash errors in your JavaScript code. To become an advanced JavaScript debugger, you’ll need to know about the debuggers available to you, the typical JavaScript debugging workflow, and code requirements for effective debugging. In this article, we’ll discuss advanced debugging techniques for diagnosing and treating bugs using a sample web application.
On accessibility
This article highlights strengths and differences between debugging tools, and shows how we perform advanced JavaScript debugging tasks. Our methods often rely on the mouse; if you prefer to use keyboard shortcuts, or if you rely on assistive technologies such as screen readers to interact with these tools, you should consult the relevant documentation to determine how (or if) these tools will work for you.
The debuggers
With an increasing selection of good debuggers available, JavaScript programmers can gain a lot from learning how to use them. JavaScript debugger user interfaces (UIs) are becoming more polished, more standardized across products, and easier to use, thus making it easier for both experts and novices to learn JavaScript debugging.
Currently, there are debugging tools available for all major web browsers. [Read more...]
