How can I use functional programming in Ruby?

You can use functional programming in Ruby by utilizing blocks, procs, and lambdas. These allow you to pass functions as arguments and create higher-order functions.

Can you give me an example of using a lambda in Ruby?

Sure! Here's a simple example:

add = ->(x, y) { x + y }
puts add.call(2, 3)  # Output: 5

This lambda takes two arguments and returns their sum.

What are some benefits of functional programming?

Functional programming can lead to cleaner code, easier debugging, and better modularity. It also encourages immutability, which can reduce side effects.

Are there any libraries in Ruby that support functional programming?

Yes, libraries like 'dry-rb' and 'ramda' provide functional programming tools and utilities that can enhance your Ruby applications.
