# pluck ```erlang pluck :: (Any key, Collection input) => Collection output ``` ## description Returns a new flattened `Collection` from an input collection of collections. The input collection is flattened by returning the value associated to the provided key of each inner collection. More simply put, `pluck(key) = map(collection => collection[key])`. ## example ```javascript import { pluck } from 'conductor' const characters = [{ id: 1, name: 'Luke' }, { id: 2, name: 'Han' }] pluck('name', characters) // ['Luke', 'Han'] ``` Suppose we have a collection of `characters`, each having a `name` and an `id`. Here, we're only interested in retrieving their names, so we flatten the input collection by returning the `name` property of each character. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
