 To make testing easier, we'll first move the reducer's code to its own module, to the file <i>src/reducers/noteReducer.js</i>. We'll also add the library [deep-freeze](https://www.npmjs.com/package/deep-freeze), which can be used to ensure that the reducer has been correctly defined as an immutable function.
