Debugging Your Code

Catching and Fixing Errors

Everyone makes mistakes while coding—it's totally normal! Debugging is the process of finding and fixing these errors. Use your browser's console to see error messages and test your code line by line. Try adding console.log statements to check what your variables hold at different steps. Stay patient and experiment until you find the solution!

Examples

  • Using console.log to find out why a score isn't updating

  • Reading error messages to fix a typo in variable names
