Async Task.Sleep() pauses everything?

Question

Async allows multiple codes/tasks to be runned at the same time.
But when I do
await Task.Sleep(1000);
inside a function. It pauses all the tasks for 1second.
Shouldn't only pause inside it's own function only?
Also, is there anyway to make a code that pauses only a specific function instead of the whole task.

Answer 1

You can create a news object that estends thread, so you can sweet only this object

Answer 2

If it is C# use Thread.Threading.Sleep(100);

Answer 3

I'm not sure but I think Task.Delay should work.
