Description

For this deliverable, we'll be refactoring our counter app to use the useReducer hook. Currently, our application is handling our state updates through the use of functions to increase and reset our counter

Your task is to take our app from updating the state with those functions to using the useReducer hook. The app is currently fully tested and the tests are working with current code. After refactoring your tests should continue to work with no changes.

Use the template to start your project.

Acceptance Criteria

  • Existing tests are passing and should continue to pass after refactoring
  • Users should be able to increment the counter with button click
  • Users should be able to decrement counter with button click
  • Users should be able to reset the counter with a button click
