React - useReducer vs useState example

In this article, we would like to compare two React hooks - useReducer and useState.

We use useReducer to keep a lot of state changes inside it. In the useState, the whole state has to be overridden. Reducer is therefore for smarter condition management. Additionally, it organizes the logic of the component.

Below we have a similar solution to the one in React documentation. What we're going to do is try to manage the state the same way the reducer function does but with a simple useState hook.

For the simplicity of the example, we've made an increasing and decreasing counter. We perform actions handled by the reducer function that modifies the current state.
