Debugging Mastery: Essential Tips and Tricks for Junior Developers in 2023

Introduction:

When embarking on the journey of software development, developers must be introduced to the art of debugging. In this article, we will explore the importance of debugging skills for young developers and provide practical tips for mastering this important part of the coding process.

Understand how the bugs behave:

Imagine you are a detective handling a case. Start by observing how well the bacteria behave. What motivates him? Under what circumstances does it occur? Understanding a bug’s pattern is the first step to unlocking its secrets.

Use Case:

Imagine your web application crashing when someone submits a form. Is it a backend authentication issue, or is the frontend not handling feedback properly? By carefully observing how the error behaves, you can narrow down your search and focus on relevant features.

Logging in Your Sidekick:

Logging is your virtual notepad on a debugging journey. Add meaningful logs to your code to track the execution flow. Don’t just post mistakes; Also list important checkpoints. This log-driven development approach could be a game changer.

Use Case:

When dealing with unexpected output, strategically placed logs can reveal the state of variables and the flow of execution. This knowledge is very helpful in identifying the source of the problem.

Version Control as Your Safety Net:

When it comes to debugging, version control is more than just a tool for teamwork. Make a branch before committing large changes. You can always revert to a stable version if your debugging efforts take an unexpected turn for the worse.

Use Case:

You're trying to correct a bug in the main functionality of your product. First, make a branch where you may test out different solutions. You may quickly revert to the stable version in case something goes wrong without endangering the project as a whole.

Leverage the Power of Extensions:

Without the proper code editor extensions, your debugging toolkit is incomplete, and Visual Studio Code (VSCode) offers a ton of them. Install debugging-specific extensions to maximize productivity and acquire information that native tools might not offer.

Use Case:

Let's say you have a front-end bug to deal with. Adding extensions such as "Debugger for Firefox" or "Debugger for Chrome" can help you debug more quickly by enabling you to examine and debug your code directly from the editor and providing you with better visibility into client-side problems.

Conclusion:

Well done, investigator! You've started the thrilling road towards becoming a skilled debugger. Recall that bugs are not enemies but rather chances for development. Not only will you be able to find the flaws with the use of strategic tools, a sharp eye, and a little bit of imagination, but you'll also become a developer who can take on any coding task. Have fun troubleshooting!
