- Higher-order functions like map, fold, and filter are essential in functional programming.
- Transducers in Clojure allow for better reusability and performance through abstraction.
- The article demonstrates how map and filter can be redefined using reduce (fold in Clojure).
- Abstraction over conj in mapping and filtering functions allows operations on various data structures, not just collections.
- Transducers are parameterized over a 'step' function, making them versatile for different data processing scenarios.
- The article provides practical examples showing performance improvements with transducers over traditional list operations.
- Transducers can be used with channels in Clojure's core.async library, demonstrating their flexibility beyond lists.
- The concept of transducers is now part of the Clojure standard library, enhancing data transformation capabilities.
