A visual demo of Ruby's lazy enumerator
Where you get to play with an interactive demo to visualize how Enumerator::Lazy helps avoid unnecessary work
In this article, we'll explore a simple visual trick to help understand how lazy enumeration works in Ruby. Enumerator::Lazy is extremely useful in scenarios where you want to build complex pipelines of data transformations or when working with large datasets. Next time you’re dealing with a large dataset or you encounter lazy in the wild, perhaps visualizing the "vertical" vs "horizontal" operation analogy will help you understand how your Ruby behaves.
