How do different programming languages handle event emitting?

Different languages have unique ways to handle event emitting. For example, JavaScript uses the EventEmitter class, while Python has the built-in signal module.

Can you give me an example in JavaScript?

Sure! In JavaScript, you can create an EventEmitter like this:

const EventEmitter = require('events');
const myEmitter = new EventEmitter();

myEmitter.on('event', () => {
  console.log('An event occurred!');
});

myEmitter.emit('event');

What about in Python?

In Python, you can use the signal module like this:

import signal

def handler(signum, frame):
    print('Signal received!')

signal.signal(signal.SIGINT, handler)

Are there any other languages you can compare?

Yes, languages like Java and C# also have their own event handling mechanisms, such as using interfaces and delegates.
