According to the challenge text:
Then create a reducer called messageReducer() that handles the state for the messages. The initial state should equal an empty array. This reducer should add a message to the array of messages held in state, or return the current state.
I find myself unsure if the instructions meant to say that state should be an empty array initially or did they mean a blank object? (isn’t state usually an object?)
Edit: I guess I’m confusing component states with the overall redux store state… hmmm.
