How can I use Ruby Lambda functions in my Rails application?

You can use Ruby Lambda functions in Rails to create concise, reusable code blocks. They are especially useful for callbacks and functional programming.

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

Sure! Here's a simple example: my_lambda = ->(x) { x * 2 }. You can call it in your controller like this: my_lambda.call(5).

What are the benefits of using Lambda functions over regular methods?

Lambda functions are more concise and can be defined inline, making your code cleaner. They also support closures, which can be very powerful.

Are there any performance considerations I should be aware of?

Yes, while Lambdas are generally efficient, excessive use can lead to performance overhead. It's best to use them judiciously.
