Iterator: Map

Run a sub-graph once per element of an input list and collect the transformed elements into a new list. Mirrors JavaScript's Array.prototype.map.

Inside the iterator scope, the auto-created Iterator::Entry exposes the current el and 0-based index; the auto-created Iterator::Collect reads the transformed element on collect to build the output list.

Example
Input:  [1, 2, 3]
Body:   el → el * 10
Output: [10, 20, 30]

Parameters​

This function has no parameters.

Input​

Arrayrequired

List to iterate over (Array or JSON array).

Value

Optional value injected into every iteration as value on the entry node.

Output​

Array

List of the per-iteration outputs collected from Iterator::Collect.
