Passo 16

Instruções

Agora preencha bugMap com duas entradas. Adicione "bee" como uma chave mapeada para uma nova instância Bee, e "spider" como uma chave mapeada para uma nova instância Spider. Passe bugEmojiElement como argumento para ambas.

O que fazer:

Testes:

Seu `bugMap` deve ter uma entrada `"bee"` definida como `new Bee(bugEmojiElement)`.
Seu `bugMap` deve ter uma entrada `"spider"` definida como `new Spider(bugEmojiElement)`.
