This hook will automatically run only when the notes variable in state changes. First we will turn our notes into a string with JSON.

Loading notes will be very similar. In order to achieve this, we can add another useEffect hook. Here the empty array [] we are passing as the second argument to our hook indicates that this function should only run on the first render of this component. Next, we parse the data into a notes array variable. Lastly, we must check if there are any notes in the browser, as we only want to set the state if so. Editing notes is going to be slightly more tricky then adding or deleting notes.

We need to display a text box for the user to edit the note in, and we should also add a button for the user to indicate when they are finished. Add the following submitEdits function to your component. This method will fire when the user clicks submit after editing a note. This will map the notes array, returning every note except the one to be updated, which it changes the text content of.

The notes array will be updated with the setNotes hook, and setNoteEditing will be reset to "" since we are no longer editing once submitted. For the display portion of our editing feature, we will be conditionally rendering an text area if the note is selected for edit, and the note otherwise.
