Introduction

In the world of web development, it's common to encounter various data structures that require transformation to fit your application's needs. One such scenario is converting a complex object returned from your backend into a more usable format – specifically, an array of objects. This guide will address how to achieve this in JavaScript, using an example to clarify the process.

The Problem

You may have data fetched from your backend in the following format:

Explanation of the Code

reduce: The reduce method is used to iterate over the entries.

Here, we split the key using a regular expression, separating the numeric part from the rest of the key.

If the numeric index exists, we update or set the corresponding object in the map.

Conclusion

Converting an object to an array of objects can seem daunting at first, but with JavaScript’s powerful methods, it becomes manageable and straightforward. The method outlined in this blog allows you to dynamically handle potential variations in the data structure, making your code more robust and adaptable.

If you encounter similar challenges in your development process, remember these techniques and adapt them to fit your unique data structures. Happy coding!
