Understanding Elixir's Streams and List Comprehensions

Konrad Sowik provides a detailed exploration of Elixir's Stream module and list comprehensions, contrasting them with the eager approach of the Enum module. Streams generate elements one by one and are lazy, helping process data with minimal memory, ideal for large data sets. By contrast, Enum processes data eagerly and instantly, which consumes more memory, particularly with large data ranges. List comprehensions offer another iterative alternative, simplified by generators and filters, and support customization with options like :into, :uniq, and :reduce. The article emphasizes that while developers often default to using Enum, it's beneficial to consider whether Stream or list comprehensions could offer a more optimized solution in certain situations.
