Transducers for Efficient Processing
Discover transducers as a powerful and efficient way to compose transformations over collections.
What are Transducers?
Welcome to Transducers! These are powerful tools in Clojure that help you process collections more efficiently.
Think of them as composable algorithmic transformations. They are designed to work independently of the source of input and the destination of output.
The Cost of Chaining
When you chain operations like map and filter on a collection, Clojure often creates a new, intermediate collection for each step. For small collections, this is fine, but for large ones, it can be inefficient.
Consider this example:
(defn main []
(let [numbers (range 1 11)
inc-numbers (map inc numbers)
even-numbers (filter even? inc-numbers)]
(println "Original: " numbers)
(println "Incremented: " inc-numbers)
(println "Even: " even-numbers)))All lessons in this course
