How to handle an event without accepting parameters?

Question

JavaScript

Retreat.
Folks, from the delegate documentation I've read, it's not clear to me why this line compiles?
Object.Event += delegate { };
Now on topic.
I need to execute the same method on different events. This can be a mouse click, pressing or releasing a keyboard button, some kind of own events. There are many such methods. And I don’t want to write a handler for each event that takes the necessary parameters (I don’t need parameters, they don’t interest me) and just launches the necessary method. I just want to bind an event to a method without parameters, and I want to do it dynamically.
Tell me how to do this? Or tell me another solution for my problem.
Thanks in advance.

Answer 1

if (t.total <= 0) {
    clearInterval(timeinterval);
    clock.innerHTML = '<p>Готово</p>';
}

Answer 2

Google Action and Func, and lambda expressions might also come in handy.

First, it is better to take and read a smart book, Richter, for example, everything is written there why and how.
Even in the error itself it is written that you need to subscribe to events like this +=, and unsubscribe -=.

class Program
    {
        static void Main(string[] args)
        {
            new TestClass();
            Console.ReadLine();
        }
}
class TestClass
    {
        public delegate void SampleEventHandler();
        event SampleEventHandler onCreate;

        public TestClass()
        {
            onCreate += delegate { Console.Write("Hello "); };
            onCreate += () => { Console.Write("World "); };
            onCreate();
        }

    }
