Higher-order functions
Learn Higher-order functions in Clojure with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.
Higher-order functions is an atomic Clojure topic inside Bindings & Functions. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what Higher-order functions changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.
Topic-specific example
(defn apply-twice [f x] (f (f x)))
(apply-twice inc 10)
Change the key input in this Clojure example and predict the result first; the named construct should be the reason the behavior changes.
