How Can I Group JavaScript Objects by Specific Keys and Nest Them for Easier Rendering?

Grouping Objects with Specific Key Names

In this scenario, we are given an array of objects that need to be reorganized for easier rendering. The objective is to group these objects based on specific key names while preserving the original key-value pairs within the nested arrays.

To achieve this, we can leverage JavaScript's native methods and functional programming. The approach involves a combination of map and groupBy from the _.js library.

The groupAndMap function takes three parameters: the input array of objects, the name of the key used for grouping, and the name of the key for nesting the objects within the group. It groups the objects by the specified key and then maps the resulting groups to create new objects with the desired key-value pairs.

The predic parameter is an optional callback function that allows for further customization of the nested arrays. In this case, we use it to invoke another instance of groupAndMap and achieve the nested grouping desired in the output.

By utilizing these functions, we can transform the original items array into the desired output where the objects are grouped by tab and section keys, and the original key-value pairs are preserved within the nested items arrays.
