Helpers are a key feature of Ruby on Rails that simplify view logic and allow you to write reusable, modular code. Their main purpose is to separate application concerns by organizing related functionality into modules. Helpers can be defined at the controller level (controller helpers) or the application level (application helpers).nnController helpers are used within a specific controller and provide methods that can be called from views associated with that controller. They enable you to write logic in one place and reuse it across multiple views.nApplication helpers, on the other hand, can be accessed by any view in your application and are defined at the application level (in 'app/helpers'). These helpers can handle more general-purpose functionality that may not be specific to a particular controller.
