How can I improve the performance of Ruby blocks?

To improve the performance of Ruby blocks, consider using lazy enumerators, avoiding unnecessary object allocations, and minimizing the use of closures.

What are lazy enumerators and how do they help?

Lazy enumerators allow you to process collections without loading them entirely into memory, which can significantly reduce memory usage and improve performance.

Can you give me an example of using a lazy enumerator?

Sure! You can use Enumerator::Lazy like this: array.lazy.select { |x| x.even? }.map { |x| x * 2 }.force.

Are there any other tips for optimizing Ruby code?

Yes! You can also profile your code to identify bottlenecks, use built-in methods instead of custom ones, and avoid monkey patching.
