Answer №1

To separate, organize and combine the key in a specific manner while also gathering the respective values, you can utilize the method of splitting the key, sorting it, and then joining it with an empty string. Here is an implementation to achieve that:

function flatSimilarKeys(object) {
    var result = Object.create(null);           // creating an object without prototypes

    Object.keys(object).forEach(function (k) {
        var key = k.split('').sort().join('');   // modifying the key by splitting, sorting, and joining

        result[key] = result[key] || [];
        result[key].push(object[k]);
    });
    return result;
}

console.log(flatSimilarKeys({ abc: 'xyz', a: 12, cba: 'xyz2', ba: 22, ab: 33, abcde: 44 }));

.as-console-wrapper { max-height: 100% !important; top: 0; }
