             the article’s show page with a success notice; if not, it re-renders the new article form with errors.
•	edit: Finds an existing article to be edited, likely to be used in a form for editing the article.
•	update: Attempts to update an existing Article with the submitted parameters from the edit form. If successful, it 
             redirects to the article’s show page with a success notice; if not, it re-renders the edit form with errors.
