Create a Dynamic Addition Quiz with JavaScript

Are you interested in developing a simple yet fun addition quiz that tests your math skills? Perhaps you’re learning JavaScript and need a project idea to practice? In this guide, we will walk you through creating a small quiz that asks a new random addition question every time a user answers the previous one.

The Problem

You want to create a quiz that:

Asks five random addition questions.

Automatically displays a new question without refreshing the page.

Shows a message upon completion of the quiz.

With a little guidance, you will be able to modify your existing code to achieve your goal smoothly. Let’s dive into how to implement this.

Understanding the Solution

To create a dynamic quiz, we need to achieve the following:

Set Up Question Logic: Create a function that generates random addition problems.

Respond to User Input: Check the user’s answer and determine if it’s correct. If it is correct, display a new question.

Track Progress: Keep track of how many questions have been answered so that you can notify the user upon completion.

Step 1: Setup Question Logic

First, we will implement a setupQuestion function that will generate two random integers and display the addition question on the webpage.

Here’s how the function looks:

Step 2: Respond to User Input

Next, modify the addition function to handle the user's input and to call the setupQuestion function if the answer is correct.

Here’s how you can do that:

Step 3: Track Progress

Finally, to ensure that the quiz ends after the user has answered five questions, you can modify your code to include a counter. Here’s a simple way to track this:

Conclusion

Congratulations on creating a dynamic addition quiz using JavaScript! With just a few lines of code, you now have an application that involves creating questions, responding to user input, and tracking progress—all without needing to refresh the page.

Feel free to modify and expand upon this idea by adding more features, such as a timer or different types of math questions. Happy coding!
