How can I improve the performance of Ruby enumerators?

How can I improve the performance of Ruby enumerators?

You can improve performance by using lazy enumerators, which process elements on demand rather than loading everything into memory.

What are lazy enumerators and how do they work?

Lazy enumerators allow you to chain methods without evaluating the entire collection at once, which saves memory and can speed up processing.

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, consider using built-in methods, avoiding unnecessary object allocations, and profiling your code to identify bottlenecks.
