In my mind, the passing of even 1 millisecond is a possible defined event but okay, if it's not formal in the JavaScript documentation as an event, I remove this from here.
  • I define a software event as any state of a program to which we can probably respond.
  • In JavaScript, how does _event delegation_ differs from more simple and probably more common event handling patterns such as:
  • * `window.addEventListener('DOMContentLoaded', () => {} );`
  • * `window.addEventListener('load', () => {} );`
  • * `window.setTimeout( () => {}, MILLISECONDS);`
  • * `window.setInterval( () => {}, MILLISECONDS;`
  • The terminology of event delegation is significantly more complex than of these and I hope to get an answer from which it will be clear to me what is the main reason that makes it more complex so to need terms such as delegation/propagation/bubbling, etc.

What is the main difference between event delegation to other event handling methods in JavaScript?
In JavaScript, how does _event delegation_, as an event handling pattern, differs from more simple and probably more common event handling patterns such as:

* `window.addEventListener('DOMContentLoaded', () => {} );`
* `window.addEventListener('load', () => {} );`
* `window.setTimeout( () => {}, MILLISECONDS);`
* `window.setInterval( () => {}, MILLISECONDS;`

The terminology (and maybe also the syntax) of event delegation is significantly more complex than of these and I hope to get an answer from which it will be clear to me what is the main reason that makes it much more complex so to need terms such as delegation/propagation/bubbling, etc.
