To pluck and group data from an array of objects in javascript in a single loop (used to remove boilerplate codes)

We can pluck any number of key, group the array using any number of keys or even group using multiple key combimations

Sample inputs and outputs

1)Input

const arrayOfObjects = [{apple:1, ball:2, cat:3, dog: "hi"}, {apple:4, ball:5, cat:6, dog: "bye"}]; const toPluckKeys = ['apple','ball']; const groupByTheseKeysIndividually = ['apple', 'ball']; const groupByCombinningTheseKeys = ['cat','dog'];

2)Function call

pluckAndGroup(arrayOfObjects, toPluckKeys, groupByTheseKeysIndividually, groupByCombinningTheseKeys)));

3)Output

{ "pluckedData":{"balls":["2","5"],"apples":["1","4"]}, "groupedByData":{ "ballgrp":{"2":{"apple":1,"ball":2,"cat":3,"dog":"hi"},"5":{"apple":4,"ball":5,"cat":6,"dog":"bye"}}, "applegrp":{"1":{"apple":1,"ball":2,"cat":3,"dog":"hi"},"4":{"apple":4,"ball":5,"cat":6,"dog":"bye"}} }, "gropedByMultiKeyData":{ "cat_dogmultiGrp":{"6_bye":{"apple":4,"ball":5,"cat":6,"dog":"bye"},"3_hi":{"apple":1,"ball":2,"cat":3,"dog":"hi"}} } }
