Feature: Merge with (Add To) Existing Item

There are many times when you need to add new parameters to an existing item that is already in the store. One way to do this is to get the existing item, add/combine/merge the new stuff, and then replace the existing item with the new merged item.

But what if we could provide that functionality in the store? Hmm, for this to work, the Data Store would have to define what types of data can be merged together and how to do it. That means the Data Store is no longer data agnostic.

As an exercise, let’s define a merge feature that allows for 2 arrays to be merged together. In this episode, we’ll talk through the scenarios and decision logic.
