Deep diff between two typescript objects with lodash, returns the difference

diff.ts

difference(newObject: any, baseObject: any) {
    function changes(newObject: any, baseObject: any) {
        return _.transform(newObject, function(result, value, key) {
            if (!_.isEqual(value, baseObject[key])) {
                result[key] = (_.isObject(value) && _.isObject(baseObject[key])) ? changes(value, baseObject[key]) : value;
            }
        });
    }

    const rval = changes(newObject, baseObject);
    let lval = changes(baseObject, newObject);
    return _.assign(lval, rval);
}

this one is also good
