A small JavaScript library implementing Clojure-style transducers for generalized data transformation across arrays, objects, iterators, and immutable data structures. It composes map/filter/take transformations without intermediate collections for better performance.

Use cases

• compose map filter take transformations over any collection
• transform data without intermediate arrays for performance
• apply the same transformation to arrays, objects, and iterators
• process infinite generators with early termination
• work with immutable-js data structures using one transformation pipeline

When to choose

• you want Clojure-style transducers in JavaScript
• you need high-performance chained transformations without intermediate collections
• you need one transformation pipeline that works across multiple data structure types

When to avoid

• you need a maintained library with recent updates or active support
• you just need simple array operations that native JS or lodash already cover
• you need lazy streams with rich operators rather than transducer semantics
