What does-y mean when installed in apt-get

There is a command sudo apt-get install -y nodejs, what is the-y parameter for?

Without it, apt-get asks a clarifying question - "do you really want to install this?"

So the key is needed to "speed up" the installation by one press of Enter.

Is it so hard to turn to Google? But it's not even that that bothers me anymore. You can not even go to Google, but to man.

Please read it:

man man 
man apt-get
http://segfault.kiev.ua/smart-questions-ru.html

In

Man apt-get

They write in plain text:

   -y, --yes, --assume-yes
       Automatic yes to prompts; assume "yes" as answer to all prompts and
       run non-interactively. If an undesirable situation, such as
       changing a held package, trying to install a unauthenticated
       package or removing an essential package occurs then apt-get will
       abort. Configuration Item: APT::Get::Assume-Yes.

And in google in the first link: https://www.opennet.ru/cgi-bin/opennet/man.cgi?topic=apt-get&category=8

-y, --yes, --assume-yes
Автоматически отвечать "да" в ответ на запрос программы; на все запросы,
которые будет выводить программа будет автоматически выдаваться ответ "да".
При возникновении нежелательной ситуации, как то: изменения пакета в состоянии
удержания или удаления необходимого для работы системы пакета, apt-get будет
аварийно завершать свою работу. 
Элемент настройки: APT::Get::Assume-Yes.
