Really cool visualization and neat to learn about lazy enumeration!

Excuse me while I go back through my code and make sure I’m using lazy enumeration wherever I’m iterating over large collections….

This sounds like a similar response I had when learning about stream editors vs text editors. It was one of the killer apps that convinced to become a CLI warrior. Opening up a large text file in Notepad took for ever, but opening the same file in vim was a nothing burger. Then, the same person that showed me that showed me sed/awk/grep, and I was off to the races.
