Problema

English 👳

When you subscribe to an observable or event in JavaScript, you needto unsubscribe to release memory in the system when you finish to use it. Otherwise, you will have a memory leak.

Português 😁

Quando você se inscrever em um evento observável ou em JavaScript, será necessário cancelar a assinatura da memória do sistema quando terminar de usá-lo. Caso contrário, você terá um vazamento de memória.

AutoLeave() 😁
