Debugging is a daily task for every developer.
In real-world projects, bugs come from user input, network issues, logic mistakes, and unexpected situations.
Learning real-world debugging examples helps students understand how professionals find problems and fix them step by step.
Common Real-World Bugs
- Form validation errors
- API response problems
- Wrong calculations
- Undefined or null values
- Incorrect conditions
- Unexpected user actions
Knowing these patterns makes debugging faster and easier.
The condition uses > instead of >=.
This prevents users who are exactly 18 from submitting the form.
By carefully checking the condition, the bug is fixed with a simple change.
This shows how small logic errors can cause real problems.
In real projects, debugging is about understanding the problem before changing the code.
By practicing real-world debugging examples, students gain confidence and move closer to becoming job-ready JavaScript developers who can fix issues quickly and professionally.
