How to Merge JavaScript Objects in an Array with Shared Keys?

Merging JavaScript Objects in an Array with Shared Keys

In JavaScript, it is often necessary to combine objects with similar keys into a single object. Consider the example given:

The goal is to reorganize this array into an "output" array where all value keys are merged into objects with shared names. The expected output would look like:

Merging the Objects

One approach to this problem is to use the following steps:

1. Iterate through each object in the array using forEach().
2. Filter the output array to find an existing object with the same name key.
3. If an existing object is found, concatenate the values of the current object to its value array.
4. If an existing object is not found, create a new object with the current object's properties and add it to the output array.
5. Handle the possibility of the value being a string by converting it to an array.

Example Code

The following code implements the described approach:

This code will produce the desired output array where all objects with the same name have their values merged.
