What are some use cases for Ruby Lambda in Rails?

Ruby Lambda can be used in Rails for various purposes, such as creating concise callbacks, handling asynchronous tasks, and improving code readability.

Can you give me an example of using Ruby Lambda in a Rails controller?

Sure! You can use a lambda to define a custom sorting method for a collection in your controller, like this: @sorted_items = @items.sort_by(&lambda { |item| item.created_at }).

What are the benefits of using Lambda over regular methods?

Using Lambdas allows for more concise code, easier inline definitions, and can help avoid polluting the method namespace with one-off methods.

Are there any performance considerations I should be aware of?

Yes, while Lambdas can improve code clarity, they may introduce slight overhead compared to regular methods, especially if used excessively in performance-critical paths.
