As a user
I want my data to persist
So that I can use this app effectively

Description

State management and flow is essential for any app to manage its data. Flux is the general standard that has been accepted for front end applications. There are different implementations of it.

Because the data flow is relatively simple, a native implementation without an outside library like redux is sufficient. This can be done using context and state.

• React Context API: Managing State with Ease
• useContext / useState

Acceptance Criteria
