Simplifying Your JavaScript Code: A Guide to Avoiding Duplication in Accordion FAQs

When it comes to programming, one frequently encountered challenge is managing code duplication. Particularly for JavaScript developers creating FAQ sections for both UK and International content, a common question arises: How can I simplify this JavaScript and not duplicate the code for different variables/IDs? Here, we’ll provide an effective solution to this problem by streamlining your approach, ensuring your code is both efficient and maintainable.

Understanding the Problem

Duplicating code not only adds unnecessary complexity but also makes maintenance more difficult. In your case, you have two separate arrays (one for UK FAQs and another for International FAQs), and the JavaScript code responsible for rendering these FAQs is almost identical. This redundancy leads to an inefficient coding structure.

The Solution: A Modular Approach

The strategy is straightforward: break down the FAQ rendering code into a reusable function. By doing so, you can utilize this function for both UK and International FAQ sections without rewriting the same logic. Here’s a step-by-step breakdown of how to achieve this.

Step 1: Organize Your Data

Let’s first organize your data into two separate arrays (which you've already done):

Step 2: Create a Reusable Function

Next, create a function that generates the HTML for the accordion items. This function takes the list of items as a parameter and returns the generated HTML:

Step 3: Render the Content Dynamically

Now, you can simply call this function for both the UK and International sections of your FAQ:

Step 4: Update Your HTML Structure

Your HTML should include two distinct divs to accommodate the rendered content for both sections:

Conclusion

By breaking out the accordion content generation into a reusable function, you not only eliminate code duplication but also improve the maintainability of your code. If you ever need to modify how the FAQ items are rendered, you only have to make changes in one place.

In summary, simplifying your JavaScript code structure not only makes it easier to read but also enhances your coding efficiency. Happy coding!
