Older collection functions were semi-lazy by default. They auto-realized in chunks of 32. Transducers wrap the functions then pass the data through, allowing full-laziness (or not if you want) by default. They also work well in cases where you don't know if/when a new value is coming, like in channels or observables. This is because they aren't necessarily wed to the seq abstraction from the get-go. |
