What is the role of helpers in Ruby on Rails? How can you use helpers to encapsulate reusable view logic?

In Ruby on Rails, helpers play a significant role in separating and encapsulating reusable view logic. They provide a way to centralize common functionality and make it available across multiple views, reducing code duplication and improving maintainability. Helpers are essentially modules that contain methods that can be called from within views, layouts, and even other helpers. Here are some key aspects of the role of helpers in Ruby on Rails: 1. Encapsulating View Logic: Helpers allow you to encapsulate view-specific logic that goes beyond simple presentation of data. They provide a place to define methods that manipulate data, perform calculations, format values, generate HTML elements, and more. By encapsulating this logic in helpers, you can keep your views clean and focused on rendering the data without cluttering them with complex code. 2. Reusability: Helpers promote reusability by providing a way to define common functionality once and reuse it across different views or even different parts of the application. For example, if you have a formatting requirement that needs to be applied to multiple views, you can define a helper method to h....
