Effective Debugging Techniques
Utilize Node.js built-in debugger and IDE tools to efficiently identify and resolve bugs in your applications.
What is Debugging?
Bugs are a natural part of programming. Debugging is the process of finding and fixing these errors in your code.
It's a crucial skill for any developer, helping you understand how your code behaves and resolve issues efficiently.
Common Error Types
Errors in code typically fall into a few categories:
- Syntax Errors: Typos or incorrect grammar (e.g., missing a parenthesis). Your code won't run.
- Runtime Errors: Happen when the program is running (e.g., trying to access a property of an undefined variable).
- Logical Errors: The code runs without crashing, but it doesn't do what you intended (e.g., an incorrect calculation).
