Debugging - The underrated skill

· Why this is often ignored and how to become better at it.

Introduction

While learning programming, most focus is placed on writing code. However, a large part of actual development involves fixing code that does not work as expected.

This is where debugging becomes important.

What debugging actually is

Debugging is not just fixing errors.

It involves:

  • Identifying where the problem occurs
  • Understanding why it occurs [Most skip this in the age of AI]
  • Applying a fix without breaking other parts

It is a structured process, not random guessing.

Common beginner approach

Initially, debugging often looks like:

  • Changing code randomly
  • Re-running multiple times
  • Hoping something works

This approach is slow and unreliable.

A more structured approach

Effective debugging involves:

  1. Reproducing the issue consistently
  2. Isolating the part of code causing the issue
  3. Checking assumptions (inputs, outputs, states)
  4. Using logs or print statements (Every dev’s best friend)
  5. Verifying the fix step by step (Tiring but worth it)

This reduces confusion and saves time, and most importantly, brings faith in your skills.

Why debugging is important

  • Real-world code rarely works perfectly on the first attempt
  • Bugs mostly come from logic, not just syntax
  • Debugging improves understanding of how systems behave, which is why devs who are good at it are good in practice.

It also helps in:

  • Writing better code
  • Anticipating edge cases
  • Improving problem-solving skills

Tools that help

Some useful debugging tools include:

  • Console logs / print statements
  • Browser developer tools
  • Breakpoints in IDEs

Even simple tools can be very effective when used correctly.

What I learned

  • Debugging is a skill that improves with practice
  • Random changes are less effective than structured analysis
  • Understanding the system is more important than memorizing fixes

Conclusion

Debugging is not usually taught explicitly, but it is essential in development. Learning how to approach problems systematically makes debugging faster and more effective.

Over time, it becomes less about fixing errors and more about understanding systems.
