What are the best practices for using closures in Ruby?

When using closures in Ruby, it's important to keep them concise and focused. Avoid capturing too many variables to prevent memory bloat.

Can you give an example of a closure in Ruby?

Sure! Here's a simple example:

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

This closure captures the variable x.

What should I avoid when using closures?

Avoid using closures for complex logic. They should be used for simple, reusable code snippets to maintain readability.

Are there performance concerns with closures?

Yes, closures can lead to increased memory usage if they capture large objects. Always be mindful of what you're capturing.
