Description

As instâncias JavaScript Date herdam de Date.prototype. Você pode modificar o objeto do protótipo do construtor para alterar as propriedades e métodos herdados pelas instâncias de JavaScript Date.

Para compatibilidade com cálculos do milênio (em outras palavras, para levar em conta o ano 2000), você sempre deveria especificar o ano de forma completa; por exemplo, usar 1998 e não apenas 98. Para ajudar a especificar o ano de forma completa, o JavaScript inclui os métodos getFullYear(), setFullYear(), getUTCFullYear() e setUTCFullYear().

Começando no ECMAScript 6, o objeto Date.prototype é ele mesmo um objeto ordinário. Não é uma instância de Date.
