Usage

const ReformatArray = require('reformat-array');
const reformattedArray = ReformatArray.mapToArray(array, key, target);

The following code takes an array of objects and creates a new array containing the newly reformatted objects.

const ReformatArray = require('format-array');

const countries = [{code: 'UK', nEntries: 10}, {code: 'FR', nEntries: 15}, {code: 'ESP', nEntries: 4}];

const reformattedArray = ReformatArray.mapToArray(countries, 'code', 'nEntries');

// reformattedArray is now [{UK: 10}, {FR: 15}, {ESP: 30}]
// countries is still [{code: 'UK', nEntries: 10}, {code: 'FR', nEntries: 15}, {code: 'ESP', nEntries: 4}]

The following code takes an array of objects and creates one dictionary containing the newly reformatted objects.

const ReformatArray = require('format-array');

const countries = [{code: 'UK', nEntries: 10}, {code: 'FR', nEntries: 15}, {code: 'ESP', nEntries: 4}];

const dictionary = ReformatArray.mapToDictionary(countries, 'code', 'nEntries');

// dictionary is now { UK: 10, FR: 15, ESP: 30 }
// countries is still [{code: 'UK', nEntries: 10}, {code: 'FR', nEntries: 15}, {code: 'ESP', nEntries: 4}]
