Introduction

Understanding the JSON Structure

Before diving into filtering, let's take a look at the JSON data we'll be working with. Here's a simplified version of what your JSON might look like:

In the above structure, each product has an id, name, price, and type, which will help us filter products based on their categories.

Filtering Products in the Main View

Now comes the important part: displaying these cards in your main view. Instead of using v-if and v-for on the same element (which can be computationally heavy and lead to performance issues), we'll use JavaScript's filter method.

Example of Filtering

Explanation:

Using filter: In the code above, we use the filter method to create a new array that includes only products whose type is 'computer'. This array is then used to render the Card components.

Efficient Rendering: By filtering the data this way, Vue only needs to process the array once, improving performance.

Conclusion

Feel free to implement additional categories by simply adjusting the filter conditions based on your JSON data. Happy coding!
