    object-cartographer

    map, reduce, and filter for objects, wrapping Object.entries().reduce()

    Usage

    const {
        mapObject,
        filterObject,
        reduceObject,
    } = require('object-cartographer');
     
    const colors = {
        red: 'ff0000',
        green: '00ff00',
        blue: '0000ff',
    };
     
    mapObject(colors, ([key, value]) => ({ [value]: key })) ===
        {
            '0000ff': 'blue',
            '00ff00': 'green',
            ff0000: 'red',
        };
     
    filterObject(colors, ([key, value]) => key !== 'red') ===
        {
            green: '00ff00',
            blue: '0000ff',
        };
     
    reduceObject(colors, (acc, [key, value]) => [...acc, key], []) ===
        ['red', 'green', 'blue'];

    For more use cases check index.test.js

    Advanced usage

    Just like with normal map, reduce, and filter, you can retrieve both the index and the original object as extra parameters in the callback. Be warned! Objects in Javascript don't have a guaranteed order so it's very unlikely you want to use the index
