It's using the event listener properties like "onclick" or "onload" as "@" gets replaced with "on" in the code from what I see so you will have this more oldschool event handling: https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Bu...

it also has some additional things here:https://github.com/nuejs/nuejs/blob/a5c844494852cdbe3282fdc5... so might not work the same way, didn't spend much time to check it just a glance.
