Objectives

1. Practice writing reducers

Instructions

It's time to build out some reducers. We're developing an app that allows you to write a list of ingredients to buy at the store.

Write your code in src/reducers/index/js

Some notes:

• Reducers take in two arguments: state and action
• Reducers must pure
• For this application, your state should default to an empty array
• Your reducer should be able to handle
  • Unknown actions
  • An 'ADD_INGREDIENT' action
  • A 'REMOVE_INGREDIENT' action

In terms of functionality, a user should be able to add an ingredient and remove it by clicking on it. Use the tests as a guide. We've built out the components and relevant actions. Once you're passing the tests, run npm run start to see your app in action!
