How to Push an Entire JSON Object into Another Object in Angular

When working with Angular and TypeScript, handling JSON objects is a common task. However, it can get tricky, especially when trying to push one JSON object into another. If you've found yourself struggling to merge different JSON structures, you're not alone. This guide will walk you through the process step-by-step, helping you to understand how to efficiently manipulate nested JSON objects in your Angular applications.

Problem Overview

Let's consider a scenario where you have a multidimensional JSON object, and you want to insert one of its items (let's call it item3) into another item (item2). Here’s an example of what your original JSON object looks like:

You want to adjust this object so that item3 is now nested within item2, resulting in the following structure:

Solution

Step-by-Step Solution

Define Your Input Object: Start with your original JSON structure.

Transform with reduce(): Iterate through the entries and build a new object based on the conditions you define.

Here’s how you can implement it:

Explanation of the Code:

input: This is the original JSON object you wish to manipulate.

reduce():

Accumulator (acc): Starts as an empty object.

Condition: If the current key is item3, it merges item3 into item2.

Otherwise, it simply adds the current key-value pair to the accumulator.

Result

When you run the above code, the console will log the newly structured output, where item3 is successfully nested within item2.
