The Problem

Our goal is to take two JSON arrays:

The first array contains detailed information about different requirements.

The second array holds matching details for those requirements, identified by their Requirement_id.

Here’s a quick look at the expected output:

The merged object should contain all relevant details from the first array.

Additionally, the merging process will account for categories and matching values, ensuring that any duplicates are consolidated under their respective Requirement_id.

Example Data
