Learning Redux

Wrapping our reducer with undoable

Now, we wrap our reducer with the undoable higher-order reducer from the redux-undo library.

Consider the following import statement:

import undoable from '../undoable'

Replace it with the redux-undo import:

import undoable from 'redux-undo'

We have already wrapped our reducer with the undoable function in the preceding section:

const appReducer = combineReducers({  counter: undoable(counterReducer),})

Ensure that the highlighted code in the preceding code is present.
