Transforming an Array into Subarrays Based on Value Ranges in JavaScript

In the world of programming, data manipulation is a fundamental skill. One common task you might encounter is organizing an array of objects into subarrays based on a specified range of a key value. If you've found yourself asking questions like, “How can I categorize items in an array based on certain criteria?” then you’re in the right place!

In this guide, we'll explore how to split an array into subarrays based on the value of a key called Open, which represents the number of open cases. We have defined specific ranges for categorization: less than or equal to 10, between 11 and 29, and greater than or equal to 30.

Understanding the Problem

You're working with an array of objects that looks like this:

The Solution: Splitting the Array

To achieve this categorization, we can utilize the filter method in JavaScript, which creates a new array with all elements that pass the test implemented by the provided function.

Running the Code

Here is the JavaScript code that accomplishes this task:

Breaking Down the Code

Creating a New Array:

var newData = []; initializes an empty array that will hold our subarrays.

Filtering the Data:

Conclusion

Organizing an array into subarrays based on key value ranges in JavaScript can be accomplished easily using the filter method. This example demonstrates how you can categorize your data effectively, making it easier to manage and analyze. By breaking down the problem and applying clear logic, you can handle similar tasks with confidence in your future programming projects!

Happy coding!
