clojure - Scala的zipWithIndex的Clojure等效项是什么？

Question

Scala Seq 具有zipWithIndex方法:

def zipWithIndex[A1 >: A, That](implicit bf: CanBuildFrom[Seq[A], (A1, Int), That]): That

Zips this sequence with its indices.

returns: A new sequence containing pairs consisting of all elements of this sequence paired with their index. Indices start at 0.

Example: List("a", "b", "c").zipWithIndex = List(("a", 0), ("b", 1), ("c", 2))

Clojure中的等效功能是什么？

Answer 1

Clojure的 map-indexed 将为您提供集合中元素的索引列表。

user=> (map-indexed vector "foo")
([0 \f] [1 \o] [2 \o])
