Troubleshooting JavaScript: Why Your Incorrect Answer Counter Doesn’t Increment Like Your Correct Answer Counter

When working on interactive web applications, particularly quizzes, it’s common to implement score trackers for both correct and incorrect answers. However, it's not unusual to face issues with counters failing to increment properly. If you're experiencing this problem with your incorrect answer counter, fret not! This blog will help elucidate the problem and provide a straightforward solution.

Understanding the Problem

In your JavaScript quiz application, you have implemented counters to track the number of correct and incorrect answers. While the correct answer counter is functioning properly, the incorrect answer counter isn't incrementing as expected. This can lead to confusion during testing.

The code snippet shared indicates that you have correctly set up functions and DOM elements for tracking scores:

Despite this, the incorrectScore() function is not called when an answer is incorrect.

The Solution

Adding an Else Statement

The issue stems from the lack of an else part in your if statement, which currently only executes the correct answer logic when an answer matches. To correct this, you need to add an else clause to handle the situation where an answer is incorrect. Here's how you can update your code:

Code Breakdown

If condition: Checks whether the selectedAnswer matches the currentQuestion.answer.

If true, it increments the correct score and updates the UI accordingly.

If false (the answer is incorrect), it calls the incorrectScore() function to increment the incorrect answer counter.

Complete Function Example

Here is how the full function might look once you include corrections:

Updating the UI

Ensure that in your HTML, you have corresponding display elements for both correct and incorrect scores:

Conclusion

By implementing an else statement in your conditional logic, you can successfully manage both correct and incorrect answer counters in your JavaScript application. This not only improves the functionality of your quiz but also enhances the user experience by providing accurate feedback on their performance.
