Curriculum

Introduction to Debugging

This introductory section lays the groundwork for your debugging journey. You'll start by understanding the importance of debugging and its role in efficient development. Dive into common debugging techniques, including the crucial skill of mentally executing code. We'll also explore the fundamentals of code execution, setting the stage for deeper understanding.

Decoding Error Messages

Mastering the art of reading error messages is crucial for any debugger. This section breaks down different error types, such as Undefined Variable Errors, Syntax Errors, Type Errors, Network Errors, and Infinite Loop Errors. You'll learn to decipher these messages and gain valuable insights into the root cause of your code issues.

Navigating the Stack Trace

This section provides a deep dive into the Stack Trace, a vital tool for debugging. You'll understand what a Stack Trace is, how it provides a roadmap to the source of errors, and how to effectively read and interpret the information it offers.

Efficient Codebase Navigation

To effectively debug, you need to navigate your codebase with ease. This section equips you with essential navigation techniques, such as 'Find in Project', 'Go to Definition', 'Go to file', and 'Go back and forth', helping you quickly locate and analyze code snippets relevant to your debugging process.

Debugging with Logs

Learn the power of logging in debugging. This section explores the use of 'console.count', 'console.trace', and other logging methods for identifying and tracking code execution. You'll gain practical experience through hands-on debugging exercises using logs, solidifying your understanding of this valuable technique.

Harnessing the VS Code Debugger

VS Code's built-in debugger is a powerful tool for efficient problem-solving. This section will guide you through its features, including setting breakpoints, conditional breakpoints, logpoints, and mastering the debugger controls. You'll also learn how to use the debugger console, watch variables, and effectively debug both caught and uncaught exceptions. Hands-on exercises solidify your understanding by guiding you through fixing bugs using the VS Code debugger.

Mentally Executing Code: A Crucial Skill

This section delves into the art of mentally executing code, a crucial skill for debugging. You'll learn how to evaluate code when multiple elements are in play, focusing on analyzing the output and understanding the flow of execution. This ability is essential for identifying potential errors before they occur.

Mastering Chrome DevTools

Explore the depths of Chrome DevTools, a powerful debugging tool for web developers. This section will cover breakpoints, logpoints, debugger controls, the console, watching variables, and debugging caught and uncaught exceptions. You'll learn how to use Request breakpoints, Event breakpoints, and DOM breakpoints for effective web debugging. Hands-on exercises solidify your understanding by guiding you through fixing bugs using Chrome DevTools.

Extra Tips & Tricks

This section delves into valuable extra techniques and best practices. You'll learn how to use Chrome DevTools to debug Node.js processes, how to inspect pages on your iPhone using Safari, and the importance of following the DRY (Don't Repeat Yourself) principle for cleaner and more maintainable code.

Conclusion

This section concludes the course with a recap of the key skills and knowledge you've gained. You'll emerge as a confident debugger, equipped to tackle any code issue with proficiency. Don't forget to check out the bonus content for even more insights and resources.
