Visualizing Ruby's Lazy Enumerator: A Simple Trick

This article uses an interactive demo to explain Ruby's lazy enumerator, `Enumerator::Lazy`. Unlike default eager enumeration, lazy enumeration only computes elements when needed, avoiding unnecessary work, especially beneficial with large datasets or complex data transformation pipelines. The article visually demonstrates the difference using 'vertical' and 'horizontal' analogies and suggests resources for a deeper dive into Ruby's lazy implementation.
