Debugging is not just about fixing errors — it is about finding problems quickly and preventing them in the future.
Professional developers follow certain debugging best practices that save time and reduce frustration.
Learning these habits early helps students become confident and efficient developers.
Debugging Best Practices
- Read error messages carefully
- Reproduce the problem step by step
- Use console.log() to check values
- Use breakpoints instead of guessing
- Fix one bug at a time
- Test your code after every fix
- Keep code simple and readable
These habits make debugging faster and easier.
Here, changing code randomly without understanding the issue wastes time.
This approach often creates new bugs instead of fixing the real one.
Here, the developer checks values and logic before changing the code.
This makes the bug easy to identify and fix correctly.
These examples show how following debugging best practices makes problem-solving easier.
By building good debugging habits, students gain the ability to fix issues faster and write stable, professional JavaScript applications with confidence.
