In this post, we'll dive into how you can generate multiple math problems with just a single function using vanilla JavaScript. If you've ever wanted to populate your webpage with several math problems that refresh upon a button click, you're in the right place! The Problem: Generating Multiple Math Problems In the original code provided, only a single math problem was generated. This is a common scenario where you’d want to display multiple instances of the same type of content—like math problems—simultaneously. The goal is to find a way to loop through the desired number of problems and display unique calculations in each one. Here's the initial code snippet that was causing the issue: [[See Video to Reveal this Text or Code Snippet]] As you can see, rand1 and rand2 were calculated outside of the loop, causing every problem element to display the same sum. Now let’s get to the solution! The Solution: Revised Code for Generating Multiple Problems To ensure each problem has unique values, we need to move the random number generation inside the loop. We'll adjust our code accordingly to achieve this. Here’s the corrected approach: Updated JavaScript Code [[See Video to Reveal this Text or Code Snippet]] Explanation of the Changes Moved Random Generation Inside the Loop: By placing the generation of rand1 and rand2 inside the forEach loop, we ensure that each problem gets different values. Selector Correction: Make sure that you are targeting the correct class name in your selector (i.e., .problem instead of .problems). Event Listener on Load: The event listener is set to call getAddition() when the window loads, ensuring that problems are generated immediately upon page load. HTML Structure To integrate this JavaScript into your HTML, ensure your structure looks something like this: [[See Video to Reveal this Text or Code Snippet]] Conclusion This approach lets you seamlessly generate multiple distinct math problems with minimal code and effort. By simply clicking the "New Problem" button, users can enjoy new calculations every time! So go ahead and try it out, and see how simple yet effective this solution is for creating engaging content in your applications. Remember, with JavaScript and a little creativity, the possibilities are endless!
