Recuperar todos os valores do objeto

Tive uma situação em que precisei recuperar todos os valores de um objeto, mas esse objeto tinha vários níveis.

O que fiz então foi, criar uma recursividade, verificando cada nó do objeto, se o nó fosse o tipo Object, como quase tudo no JS é, a função é novamente chamada entrando em um loop até que todos os nós fossem processados e seus valores armazenados.

O reduce permite um valor inicial, então usando o concat e o valor inicial como um array vazio
