Finding and fixing errors
What is Debugging?
Debugging is the process of identifying, analyzing, and fixing errors in code or configuration. Developers use logs, browser devtools, tests, and debugging tools to understand why something doesn’t behave as expected and how to correct it. Debugging is a daily part of software development.
Why It Matters
Without debugging, it’s impossible to ensure stable, high-quality software. Debugging prevents outages, incorrect data, and poor user experience, and can also uncover security issues.
