Transducers for Composable Transformations
Transducers let you compose data transformations independently of the source or destination collection. This lesson builds on functions and laziness to show efficient, reusable pipelines.
The Pipeline Problem
Chaining map and filter creates intermediate sequences. Transducers describe the transformation once and apply it without those intermediates.
A Transducer Is a Recipe
Calling map or filter with a single argument returns a transducer, a transformation recipe with no collection attached.
