The article highlights the benefits of using transducers instead of lazy-seq operations in Clojure programming. Transducers are described as better building blocks for composing Clojure programs due to their numerous advantages. The author recommends defaulting to writing transducers and provides several reasons to support this approach. Firstly, the article emphasizes that eagerness is usually preferred over laziness in Clojure, as lazy-seq operations can lead to issues with data evaluation and side effects. Secondly, the performance benefits of transducers are highlighted, with an example showing that transducer-based code can be significantly faster and use less memory compared to lazy map operations. By defaulting to transducers, developers can improve the performance and efficiency of their Clojure programs. This article is a valuable resource for developers looking to optimize their code and stay updated with the latest practices in Clojure programming.
