Ruby's Bar

Ruby's `bar` method is used in Ruby programming within certain classes, like `Enumerable`, to create a new object that maintains the same type as the original but with modified data. It acts as a namespace for building chaining methods, allowing developers to create custom collection types that can process data seamlessly. Think of it as a way to customize how data is transformed and collected, providing flexibility for complex data manipulation while preserving the original object's structure. This promotes clean, readable code and efficient data handling in Ruby applications.
