• Use a debugger to pause program execution at specific points to inspect variables and call stacks.
• Insert print statements throughout the code to output variable values.

16. What is the role of log analysis in debugging?

• Examine log files for error messages, stack traces, and other debugging information
• Monitor system performance for improved efficiency
• Analyze code structure to improve readability
• Review user feedback to identify potential issues

17. How do you use profiling for debugging?

• Change the code structure without any analysis to see if it works better.
• Comment out sections of code to bypass potential errors during execution.
• Use random values to test different parts of the software quickly.

• Adobe Illustrator Developer Tools
• Firefox Developer Tools

21. How do you use console methods for debugging JavaScript?

• Write comments in the code to explain functions and variables for better clarity.
• Use `console.log()`, `console.error()`, `console.warn()`, `console.table()`, and `console.time()` and `console.timeEnd()` to inspect values, variables, and data structures at various points in your code.
• Use different programming languages to rewrite the code for better performance and bug detection.
• Create external documentation that outlines potential errors and solutions to aid in troubleshooting.

22. What is the role of the debugger statement in debugging JavaScript?
