Viber has a remote chat?

Question

Viber

I opened a viber today, I look in chats, some unknown number appeared to which a message was sent that was deleted, I looked at the date of sending about a year ago, I remembered that such a number was in contacts, but the chat itself was also deleted, backups were never made - I can’t understand where did it get recovered from?

Answer 1

It is not necessary to know all these things by heart, but you need to know that they exist at all, and know where to read about them. Situations like "you ended up on a desert island without the Internet and you urgently need to program a combat robot in javascript" do not even occur in the movies. You can always google "mdn math" and open a page that lists all the methods of the Math object, for example.

I paid more attention to comparison operators, the typeof operator, and type conversions.

Звучит примерно как "выучил буквы А, Б, В, подскажите какие еще буквы мне учить". Скорее всего придется познакомиться со всеми операторами, а потом еще учить как их в выражениях применять.
