result = "Invalid Input"; // Error handling

                      }
                      setText("outputResult", "Converted Temperature: " + result);
                  });
                  Step 4: Test the Converter

                     Run the app and input a temperature value.

                     Select conversion options from the dropdown menus.

                     Press the Convert button to verify:

                    o   Correct conversions between units.
                    o   Proper error messages for invalid inputs.





                  Step 5: Troubleshooting Tips

                     Issue: The app is not responding to clicks on the "Convert" button.
                    o    Solution: Check that the button's ID matches btnConvert in both the design and code.

                     Issue: The output always shows "Invalid Input."
                    o    Solution: Ensure the dropdown menu IDs (convertFrom and convertTo) are correct
                        and initialized in the code.

                     Issue: Conversion results are incorrect.
                    o    Solution: Verify the mathematical formulas in the code for accuracy.

                     Issue: The app crashes or shows errors.

                    o   Solution: Use console.log() to debug the variables and confirm correct data flow.
                     Issue: Nothing is displayed in the result label.

                    o    Solution: Check the ID of the result label (outputResult) and ensure it matches the code.
                  Step 6: Enhance the Temperature Converter

                     Add Features:

                    o   Include a "Clear" button to reset inputs and results.
                    o   Add a button to swap the convertFrom and convertTo dropdown values.

                     Improve UI:
                    o   Highlight dropdown menus or results for better visibility.

                    o   Add animations for button clicks.
                     Error Handling:

                    o   Display warnings for empty inputs.
                    o   Add tooltips or placeholders to guide users.
