Developers Use Transducers To Build Efficient Pipelines

This article explains transducers in JavaScript, showing how reducer decorators compose map and filter operations without creating intermediate collections. It walks through reducers, mappers, and filters with code examples—calculating the sum of squares from 1 to 10 (385)—and demonstrates composing reusable, single-pass pipelines that avoid memory duplication using reduceWith and decorated reducers.
